Hiya all.

I know that it's an ancient card but I don;t have the money to upgrade it as of yet. I'm running a SIS 6326 4MB AGP Graphics Card and whenever I play back any video that isn't MPEG I get massive colour saturation and the video is completely unwatchable. I've got the latest drivers that XP provided, latest Direct X (9.0c) and I know for a fact that the AGP slot is working.
I have all codecs needed to view the files but am unable to.
It doesn;t matter what player I run it through, WMP, MPC, BSPlayer...it's all the same thing.
Please somebody help me sort out the problem, I'm at my wits end.

Try downloading the drivers from:
http://www.sis.com/download/

they dont have XP listed, so try NT 4.0 instead, or 3.5 or 2000.

The drivers that XP includes are usually pretty old ... unless you got them from windows update.

The only thing that would help would be new drivers, or just buy a new card. The drivers should work though. You can also try a different player ... maybe it's screwed up. I know that my windows media player is always screwed up, so I use http://www.jetaudio.com/

The res display/color depth may be set too high so doesn't support it. WINXP likely using its own WDM drivers.
Like TExMex says, go to SIS website and use the WIN2000 graphics driver which is dated Nov 2002.


*SIS doesn't even support that one and was not designed to run on WINXP.
Video cards are not expensive so I suggest buying a new one.

If you cannot find a driver that will install, and let you adjust these factors, it looks like - based on what web searches say, I have never touched one of these - you need a card that you can manage under XP - that is one that has valid XP drivers.

here's another forum posting, pointing the same direction as Mischcabob and TexMex are:

I did find an interesting side note we may want to file for future reference, which kind of emphasizes the point:

"Heed this warning. With modern PCs, there are very few cases in which installing a non-defective PC peripheral that physically fits can damage the peripheral or the system. One big exception is motherboards that use the Intel 845 or 850 chipset or the nVIDIA nFORCE chipset. Due to improper design and keying, a few AGP adapters that are actually 3.3V devices are keyed such that they can fit a 1.5V slot. Furthermore, they handle the A2 line incorrectly. The upshot is that installing one of these cards in an Intel 845, Intel 850, or nVIDIA nFORCE motherboard may destroy the AGP adapter and/or motherboard. The following AGP adapters have been reported to exhibit this problem:

* some nVIDIA Riva TNT2 adapters
* all nVIDIA Vanta and Vanta LT adapters
* all SiS 6326 and SiS 305 adapters

* all S3 Savage4 adapters earlier than revision 3.0
* all 3dfx Voodoo3, Voodoo4, and Voodoo5 adapters
* some nVIDIA GeForce2 GTS and GeForce2 Pro adapters

Note that this list may not be complete, and that the documentation that came with the adapter may have been printed before the problem came to light. Before you install any older AGP adapter in one of these motherboards, verify on the card and motherboard manufacturers' web sites that the card is compatible with the motherboard. "

Let's hope this information is irrelevant to any problem we see with these boards.

hello,
I know that this problem happens when you activate the YUV12 output mode for video playback, try to desactivate it.
