  1. i have a DV pal video segment...1 hour, 12 minutes long. When i convert it to DVD NTSC, the duration of the new mpeg2 file is 44 minutes total...no frames lost...both videos are the same.
    why is this happening???? i play the avi in windows media and the mpeg2 in Windvd....while playing both at the same time...they run at the same speed....but the counter in winDVD goes slower...

    thanx a lot if u can help me.

    Not sure if this is correct, but I used google and typed in ntsc vs. pal

    This was on one of the pages...

    The three differences between NTSC discs and PAL discs are: 1) Picture size and pixel aspect ratio (720x480 vs 720x576), 2) Display frame rate (29.97 vs 25), 3) surround audio options (Dolby Digital vs MPEG audio). Video from film is usually encoded at 24 frames/sec. but is preformatted for one of the two display rates. Movies formatted for PAL display are usually sped up by 4% at playback, so the audio must be adjusted accordingly before being encoded. All PAL DVD players can play Dolby Digital audio but not all NTSC players can play MPEG audio. PAL and SECAM share the same scanning format, so discs are the same for both systems. The only difference is that SECAM players output the color signal in the format required by SECAM TV's.

  3. thanx for taking time to search for this, maxx. I appreciate it.

    Weird thing is, most of those diferences u quoted between pal and ntsc, were of my knowledge (xcept for the 4% speed difference)....but then again, this weird behaviour has no explanation yet....

    IŽll keep on searching for a reason to this...thanx a lot again for your time.
