  • Last attempt to get some peace in my soul

    I've been asking about this before, but it's driving me crazy and I havn't found a sollution yet. I've tried the matrox support and they couldn't come up with anything, so I really hope you could help me out here.

    I've got some seriuos jerkiness problems when using DVDMax. All other modes work fine, ie. Multidisplay and fullscreen player. The problem comes up whatever I try to output, weather it's DVD or a movie played from my harddrive.

    There are no IRQ conflicts or sharings anywhere in my system, and it's runs like a dream in all other aspects. It doesn't matter wheather I shut down all other running processes or not. The problem has followed me from when I got the card, throughout all driver and bios upgrades, currently I'm using PD6.23. It doesn't matter if I remove the overclocking of my CPU.

    I've tried fiddeling with the settings in the "DVDMax Options" window and I think I've covered all possible combinations.

    Previous suggestion was NTSC->PAL conversion clipping a coulple of frames/sec. but I don't buy that since it works with Multidisplay.

    PLEASE HELP!

    what do you mean with 'snce it works with multidisplay'?

    When you output NTSC material on a PAL tv, you WILL get jerkiness, because the G400 doesn't support PAL60 (yet?).

    here's a very simple explanation of what's happening when you're outputting NTSC material to PAL:

    NTSC film based video files, i.e. 24fps. -> Matrox G400 Maven -> doubles done frame every second to convert it to 25fps -> PAL output.

    NTSC video based video files, i.e. 29.970fps -> Matrox G400 Maven -> drops one frame every six seconds, to convert to 25fps -> PAL output.

    So in either case, you get doubled or dropped frames. I myself am less bothered with the NTSC 29.970 to PAL conversion than the NTSC 24fps to PAL conversion, because the one doubled frame with NTSC film based stuff is REALLY annoying. You could suggest to matrox that as long as they don't support PAL60, it may be better to do a 3:2 pulldown on the 24fps to get 30 fps which is then converted to 25 fps for PAL (if that's a good idea and technically possible in the first place).

    Not to mention this, PAL material on PAL tv output has some bug in the G400 driver, which causes some periods of stuttering once every 5 and a half minute (that's what I get at least).
