Nvidia 8800 GTS/GTX does not play back Video or live TV

Description
Using the latest driver 9746 video will not playback in Myth. The same recorded video will playback when using mplayer.
This is part of the log from mythfrontend
X Error: BadMatch? (invalid parameter attributes) 8 Major opcode: 140 Minor opcode: 14 Resource id: 0x197
Opcode 140 for me is XVideo. If Idisabled XVideo in xorg.conf then Myth was able to play back video. Albeit a very slow rate.

I also get this error however playback is not effected. I while ago when researching this error message I came across a post saying this error message is harmless and due to some development being done in the openGL renderer. This may be a red herring to your playback problems.
Here is the error message I get:
X Error: BadMatch? (invalid parameter attributes) 8
Major opcode: 140 Minor opcode: 14 Resource id: 0x1a2
What is your video card?

Replying to danielk:
Does XVideo work if you turn off Xv picture attributes in the Playback config?
I believe XV picture attributes is off. I do not have Xv Picture controls checked off in Playback config.

I am not using the Opengl vsync timimg.

Sorry I was wrong about this being related to development. That was the message 'VideoOutputXv?: XvMCTex: Init failed'

It's not the driver - it's the driver and the card combo - if you use the same driver with a 6800GT (as in my case) myth plays video fine.

Can someone experiencing this problem tell me if the attached patch makes things work for you?

This gets rid of the error message for me. I wasn't having any playback problems so I cannot comment on that.

No more error message. The preview window shows the video, as it did before. It still also shows a black screen with audio on playback.
There was this error message. I am not sure if this helps.

The XvMC OpenGL renderer message is not an error message, it just means you can't use the OpenGL OSD. If it were an error message "Error" would appear somewhere in the text. You can't use this OSD renderer anyway since XvMC is broken for the 8800 with the released drivers.
Can you try uncommenting this line in videoout_xv.cpp:
#define USE_HACK_FOR_BROKEN_I420_SUPPORT_IN_DRIVER
This will force MythTV to use an alternate color format for the XVideo buffers.

Ok, this indicates a driver problem, please report this to linux-bugs@…. Tell them that XVideo does not display video when you use the I420 planar image format in the latest drivers for your video card.
You can point them to MythTV and this ticket for a sample program.
Marking as invalid: driver bug.
Does XVideo work if you turn off Xv picture attributes in the Playback config?
