Hi guys,

I just recently took a weekend and built a new XBMC/mythbackend box. The 11-year-old xbox was getting a little long in the tooth, and I just got a new TV (A Panasonic 1080p plasma, if you care), so I figured what the hell.

Anyway, the system is based on a ZOTAC IONITX-G-E motherboard, so it supports VDPAU. I'm using the latest (256.?) nVidia drivers, and the latest Dharma SVN build. The TV card is a Hauppauge HVR-1950 MPEG2 encoder, and CPU usage isn't the issue. The encoder handles getting compressed data in, VDPAU handles getting data out. But, when watching standard television, if I pick ANY deinterlace mode, the video goes all whack (jittery and such), audio goes out of sync, until I disable deinterlacing, stop the stream completely, and open a channel again.

I have Render Method set to Auto detect, VDPAU Acceleration on, have told XBMC to adjust the refresh rate of my display, told it to sync to display (although turning this off has no effect), and the A/V sync method set to "Audio Clock". My x.org has all needed available modes, 60, 59.97, 29.97, and 30Hz available.

Here's a copy of the xbmc.log file: http://pastebin.com/GV0ubU04

Try setting scaling method to bilinear.

Switching to the bilinear scaling method allows all deinterlacing methods to work without problem.

If you guys would like any help working out the bug, just tell me what to do next.

[EDIT]Well, it seems to fix it for a while, and then it's happening again.
