H.264 Sports "Stutter"

Thanks for all the info Rel. You must be teasing us with 1.4i, since I don't see it posted nor the new epg :)

I have a stutter issue on H.264 sports. I have a similar system and was wondering which driver version for the 8600 you are using? Right now I am running 169.28 but have tried all back to 162.50 from Nvidia. I did not have the stutter for a long period of time prior.

You reference:

Video Codec.....: InterVideo (v4.0.5.43 - 23.05.2002)
Audio Codec.....: InterVideo (v4.0.11.83 - 25.02.2003)
H264 Codec......: CoreAVC (v1.6.0.0 - 29.10.2007)
Video Renderer..: Video Mixing Renderer 9
Audio Renderer..: Default DirectSound Device

Here is my codec dump:

Video Codec.....: InterVideo (v8.0.6.109 - 3/20/2007)
Audio Codec.....: InterVideo (v8.0.6.109 - 3/20/2007)
H264 Codec......: CoreAVC (v1.6.0.0 - 10/29/2007)
Video Renderer..: Video Mixing Renderer 9
Audio Renderer..: Default DirectSound Device

Those are the same codecs from when I had no stutter, save coreavc which was 1.5. But there is no difference in 1.5 to 1.6 for me. I have tried coreavc with agressive interlace on or off. It also stutters with nvidia audio as well. I purged all the ddsouce.ax except the one from 1.4h including cleaning the registry. I'm starting to think I need a fresh load of XP Pro. I can't remember when the issue started on what version of DD. I can send some very short ts clip if you want.

Arcsoft has the same problem and Cyberlink is like in slow motion. I think I'm just going to have to start fresh. I've disabled the epg dvbepg parser, set priority to normal, disabled the log, turned off virus/spy, disabled update check, disabled my internet and still stutter along. The H.264 normal programs and movies are fine it is just sports - football, basketball and hockey.

Thanks for all your hard work and all those in the DD community.

there is nothing special on upcoming v1.4i for h.264, except guids.ini :)

I use nVidia forceware 163.75 drivers (exact name: 163.75_forceware_winxp_32bit_english_whql.exe)

v1.4h should work the same way using the updated guids.ini I've posted.
those configurations were just using the default options for DD. (no need to touch anything, i.e. buffer sizes) just a clean install with default options
I have tried on FTA H.264 (on three different 1080i channels / 19 degree east / europe)
AMD x2 64 3600 - 1024 MB - WinXP sp2 - 8600GT

I had to do a clean XP install. Used 163.75 drivers + Purevideo + Intervideo and Coreavc 1.6. Now it is stutter free. Although not every feed likes intervideo - don't know why the graph won't render.
