    261040 frames is 2:25:01:10 in 30fps non-drop-frame time. It will take
    slightly longer than this to play at 29.97fps; drop-frame would be
    about 2:25:09.

    I wouldn't trust the length Windows Media Player is telling you. It
    might be chopping off the last GOP or something.

    Also, if your video ever goes through the AVI format, all bets are off
    - most AVI reading/writing software gets the frame rate slightly
