8776 XVMC dvd Playback Choppy

[publicmsu]

In both mplayer and xine, I've attempted to playback a DVD using the xvmc video output driver and in both cases the video is highly choppy!

I'm using the geforce 6600 PCIe, and when I export XVMC_DEBUG=2 and watch the xine output, it reports errors of not being able to allocate AGP DMA (for obvious reasons), and instead allocated a framebuffer DMA. Is this the proper functionality for xvmc under these conditions?

Mplayer reports that my PC is too slow to play back the DVD, however it is perfectly fine with the xv video output driver.

edit:

I receive this error when trying to use the -vo xxmc output driver.

video_out_xxmc: ERROR: Accelerated surface allocation failed.
video_out_xxmc: You are probably out of framebuffer memory.
video_out_xxmc: Falling back to software decoding.

xvmc is in slow motion and xxmc fails to work.

Try copy the .VOB files to another place on HD or another machine on the network and see if that is different.
I had slowmotion xvmc playback on my system before, and it went away when I moved the files to a fileserver. I think it has something to do with interrupts and maybe disk dma operations.

This isn't an issue with just the DVD, but also any cotent on any of my drives. It would appear as though there is an issue with xvmc.

I have the same AGP DMA message on Geforce 6150. DVDs work fluently. If Nvidia could provide any way of good deinterlacing it would be perfect.

I heard rumours that some of high models of Geforce6 has broken video processor by hardware design.
