Hello list, everytime a playback a NTSC file with 24000/1001 frames per second (fps) over my dvb rev. 1.5 the playback is jerky and I get light collums all over the picture, it looks like interference. In contrast playing 3000/1001 fps NTSC material or 25 fps PAL material over the card is just fine, playback is fluent and there's no interference. Is there a limitation to 30000/1001fps for NTSC in the dvb specs in general or is this a limitation of the TT dvb only? If this is indeed the case I'd like to bother mplayer and dvd-plugin developers with it a bit :-) Thanks Sebastian
