You use Windows Media Player 12 to play an Advanced Stream Redirector (ASX) playlist on a computer that is running Windows 7. However, Windows Media Player 12 stops playing media files before the end of the playlist is reached.
This issue occurs when the following conditions are true:
This issue occurs because Windows Media Player 12 does not correctly recognize the ASX playlist.
Windows Media Player 12 tries to determine the file type of a playlist before the playlist is completely loaded. However, Windows Media Player 12 cannot determine the correct file type until the playlist is completely loaded. If an ASX playlist contains a nested ASX playlist that contains various types of media file, Windows Media Player 12 may take a long time to load the whole playlist. This causes Windows Media Player 12 to incorrectly identify the playlist as another file type. Therefore, this issue occurs.
