[QUOTE="htpcoz, post: 28597, member: 13987"] Area: My TV MP Version: CVS build 13/12/2005 (but has done it since I can remember) Skin: BlueTwo Windows Version: Windows XP SP2, .NET 2.0 CPU Type: Intel P4 2.8Ghz Memory: 512MB, DualChannel Motherboard Chipset: ? (Intel 865) Video Card: Radeon X700 Video Card Driver: Catalyst 5.12 Video Card Resolution: 1920x1080i Video Render Type: VMR9 Video Codec Type & Version: Nvidia Audio Codec Type & Version: Nvidia TV Card: DNTV TV Card: Haup 150MCE Optional Log: N/A Optional References:N/A Synopsis: Is anyone successful at HD playback using Nvidia codecs? I've been interested in viewing HD channels for some time now, and while most other things I find are exceptionally stable, one thing I've not been able to get going successfully is HD (1080i or 576p) playback. What I find is that when attempting to use my Nvidia codec on HD channels, the playback is not smooth, it is very jumpy. The display statistics are not showing any dropped frames, but the playback shows continuous jerkyness. At this time CPU is showing around 30-40% (on a HT processor so that is realistically closer to 70 percent or more), but it is certainly not maxing out on CPU. The Nvidia codec is flawless on SD channels, with CPU around 15% If I move to another codec (eg the DNTV Live codec that comes bundled with the card's software) then the playback of HD channels is fine, although there are other issues with the zoom not being set correctly between my digital and analog cards (probably an issue with the codec being specifically developed for the digital playback). The Nvidia seems to me to be generally the best in terms of quality, but does appear to have issues with the HD material. Is anyone successfully playing HD material through the Nvidia codec. I know there are a few settings that can be applied on the property page of the Nvidia codec, and I'm wondering if one of my settings is imposing too high a load on the codec for the greater bandwidth HD material. Any thoughts? [/QUOTE]
