CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This is a continuation of co-pending U.S. application Ser. No. 10/670, 973 filed Sep. 25, 2003, which is incorporated by reference. Further, pursuant to 35 U.S.C. .sctn.119(a), this application claims the benefit of earlier filing date and right of Korean Patent Application No. 10-2003-14164, filed on Mar. 6, 2003, the content of which is hereby incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION Field of the Invention [0002] The present invention relates to a method for setting a playback environment for reproducing audio/video (A/V) data in an interactive or enhanced recording medium, such as an interactive digital versatile disk (also known as I-DVD or Enhanced Digital Versatile Disk (ENAV)), along with additional contents associated with the A/V data. of permanently recording and storing not only high-quality digital audio data, but also high-quality moving picture data. [0003] A DVD includes a data stream recording area for recording a digital data stream, such as moving picture data and a navigation data recording area for recording navigation data needed for controlling playback of the moving picture data. A typical DVD player first reads the navigation-data recorded on the navigation data recording area, if the DVD is seated in the player, stores the read navigation data in a memory provided in the player, and reproduces the moving picture data recorded on the data stream recording area using the navigation data. [0004] The DVD player reproduces the moving picture data recorded on the DVD, such that a user can view and hear a movie recorded on the DVD. Information (control or additional information) associated with the playback of audio/video (A/V) data recorded on the DVD can be recorded as a file written in a hypertext markup language (HTML) on the DVD. Standardization work of an interactive digital versatile disk (I-DVD) is ongoing. The A/V data recorded on the I-DVD is reproduced according to the user's interactive request. Where I-DVDs are commercialized, the supply of contents through digital recording mediums will be more prevalent. [0005] A method is being developed for seamlessly and continuously reproducing A/V data in an I-DVD, at the time of a synchronous playback operation for the A/V data and additional contents, i.e., ENAV data, associated with the A/V data recorded on the DVD. Various playback environments must be set before the data of the disk is reproduced so that the A/V data and the ENAV data on the disk can be seamlessly reproduced and outputted under limited resources of the player. SUMMARY OF THE INVENTION [0006] In accordance with one or more embodiments, a method for connecting a media player to a remote server comprises processing a request for connecting to an remote server while reproducing data recorded on an enhanced navigation medium; processing connection information recorded on the enhanced navigation medium to determine whether connection to the remote server is permitted; and requesting connection to the remote server, if connection to the remote server is permitted in accordance with the connection information. [0007] The connection information is recorded in a start-up file that is read prior to reproduction of the data recorded on the enhanced navigation medium. The start-up file comprises information associated with a list of additional contents to be loaded before the data on the enhanced navigation medium is reproduced. The start-up file comprises information associated with a right to reproduce the data recorded on the enhanced navigation medium. [0008] In some embodiments, the start-up file comprises information associated with a region code, a language of the additional contents, memory management, and a file to be processed after the start-up file is processed. The connection information comprises a list of servers to which the media player may connect or alternatively a list of servers to which the media player may not connect. [0009] The data recorded on the enhanced navigation medium comprises audio/video (A/V) data. The data recorded on the enhanced navigation medium comprises additional contents associated with the A/V data, in some embodiments, for example. The A/V data and the additional contents are reproduced in synchronization. [0010] The connection information comprises at least one connection address for connecting to the remote server. The start-up file comprises the connection information, wherein the start-up file comprises information associated with a walled-garden file comprising location information about at least one server. [0011] The walled-garden file comprises information about at least one server to which the media player may connect to retrieve additional contents associated with the data recorded on the enhanced navigation medium. In one embodiment, the walled-garden file comprises information about at least one server to which the media player may not connect to retrieve additional contents associated with the data recorded on the enhanced navigation medium. [0012] The walled-garden file comprises at least one entry associated with loading information that controls access to information available on the at least one server. The loading information comprises at least a condition for loading information available on the at least one server, and at least one of a language or a profile supported by the media player. [0013] In one or more embodiments, a method for processing a connection request of an enhanced navigation media player comprises determining a current operating mode and connection limitation information, in response to a connection request for connecting the player to a remote server; and submitting the request to the remote server to establish a connection, based on the current operating mode and the connection limitation information. [0014] The connection request is submitted, if the current operating mode is an enhanced navigation playback mode. Also, the connection request is submitted, if the connection limitation information provides permission for the remote server to be contacted. That is, the connection request is submitted, if the current operating mode is an interactive disk playback mode and if the connection limitation information indicates that the remote server may be contacted. [0015] In certain embodiments, the connection limitation information is included in a start-up file residing on an enhanced navigation medium. The start-up file is read prior to the player reproducing data recorded on the enhanced navigation medium. The start-up file comprises information associated with a list of additional contents to be loaded before data recorded on the enhanced navigation medium is reproduced. [0016] In accordance with another embodiment, an enhanced navigation media player for processing data recorded on a recording medium is provided. The player comprises an audio/video (A/V) player engine; and an enhance navigation (ENAV) engine, wherein if the recording medium is not an enhance navigation medium then A/V data recorded on the recording medium is reproduced by the A/V player engine, and wherein if the recording medium is an enhanced navigation medium, then a start-up file is loaded into a first memory so that the ENAV engine can extract connection information about at least one server with additional contents. [0017] In one or more embodiments, the start-up file comprises information associated with a walled-garden list that provides the connection information about the at least one server. The start-up file may also comprise loading information that controls access to the additional contents available on the at least one server. The loading information comprises at least a condition for loading the additional contents available on the at least one server, a language condition to limit access to the additional contents available on the at least one server based on the language condition, a profile condition to limit access to the additional contents available on the at least one server based on the profile condition, and parental condition to limit access to the additional contents available on the at least one server based on the parental condition. [0018] In some embodiments, an enhanced navigation recording medium comprises audio/video (A/V) data; and connection information for controlling access to additional contents available through at least one remote server, wherein the additional contents is reproduced in synchronization with the A/V data. The connection information comprises at least a condition for loading the additional contents available on the at least one server and a language condition to limit access to the additional contents available on the at least one server based on the language condition. [0019] A profile condition to limit access to the additional contents available on the at least one server based on the profile condition, and parental condition to limit access to the additional contents available on the at least one server based on the parental condition, may be also included. In one embodiment, the connection information limits access to the at least one remote server or permits access to the at least one remote server. [0020] In accordance with yet another embodiment, a method of playing back audio/video (A/V) data recorded on an enhanced navigation medium comprises identifying a playback mode; decoding a start-up file recorded on the enhanced navigation medium, if the playback mode identifies an enhanced navigation mode, wherein the start-up file comprises first an second information; decoding the first information to determine location of at least one remote server that provides access to additional contents to be played back in synchronization with the A/V data; and decoding the second information to determine at least one condition associated with the additional contents.
