Graphics choppy video playback on TVO after upgrade

I've recently upgraded my 2500+ to a 2800+, complete reinstallation of WinXP (SP1) reinstalled all of the my standard codecs but still my 6800GT is outputting its TV signal really choppy? I have tried the orig. drivers then the most recent ones.. nothing has helped.... is there something I've missed?

 

I guess you didn't get the memo:

The on-chip video processor on your 6800 is very likely *broken*

The AGP 6800 video cards that Nvidia has made and shipped thus far (to a large extent) do not have the On-chip video processor functioning at all, despite being a feature listed on the 6800 tech specs and selling points during the then-paper launch.

All this card currently does is decode MPEG-2 - a *far* cry from what they list as features.

"The Video Processor (soon to receive a true marketing name) on the NV40 was somewhat broken, although it featured MPEG 2 decode acceleration. Apparently, support for WMV9 decode acceleration was not up to par with what NVIDIA had hoped for. As of the publication of this article, NVIDIA still has not answered our questions of whether or not there is any hardware encoding acceleration as was originally promised with NV40. So, the feature set of the Video Processor on NV40 (the GeForce 6800) was incomplete, only in its support for WMV9 acceleration (arguably the most important feature of it).

NVIDIA quietly fixed the problem in the 6600GT and since the 6200 is based on the 6600, the 6200 also features the "fixed" Video Processor with WMV9 decode acceleration support. After much explaining to NVIDIA that their credibility when it comes to the Video Processor is pretty much shot, they decided to pull the talk about the Video Processor from their launch of the 6200. As a result, you won't see any benchmarks of it here. NVIDIA is currently aiming to have us a functional driver and codec that will enable the Video Processor and take advantage of its capabilities in the next month or so; given that the feature has already been on cards (in one form or another) for 6 months now, we're just going to have to wait and see."

"The video processor on early NV40 and NV45 samples, both in retail and the reference boards shipped to reviewers, is broken. Fire up a HDTV video source using either GPU and watch CPU usage spike at near 100% utilisation. GPU-offload of video processing tasks, especially the decode assist needed for smooth playback of HDTV video, even on very fast CPUs, just isn't being performed. NVIDIA acknowledge that's the case with early NV40 (units that shouldn't have made it to retail) but insist it's working in retail samples and in NV45.

My own personal testing indicates otherwise, both with all the reference boards I have (the full gamut on both PCI Express and AGP) and any retail samples that pass by me for review. CPU usage is very high, the VP isn't working.

So testing with NV43 was always on the cards. The test? Playing back the original HDTV T2 trailer in Windows Media Player 9, along with playback of two transcoded versions (XviD and MPEG2) at their native resolutions. Software was used to monitor CPU usage for just under two minutes of playback over the three high-res streams and an average taken of the WMV9 original source results."

As you can see, the 6600GT, which is a cheaper, less-powerful card, has a fully functional VPU, while the flagship products do not. Nvidia has yet to respond to this and so I am writing you guys in hopes you can write about this - even just a blurb, to make Nvidia pay attention to the users whom they have falsely advertised 6800 featres to, yet failed to deliver at all and instead delivered with the 6600 cards.

Ahh OK, makes sense, the problem is that it was working fine with possibly different drivers and a different CPU. Will be testing later.

I'm sure I won't be so quick at picking up a brand new card from NV in the future!
