Been playing with an XBMC install this weekend.

I have an E7300 CPU on an E7AUMDS2H motherboard (nVidia 9400 IGP) with 4GB of RAM. (512MB allocated to the video section)

Played with Ubuntu, Xubuntu and Xbox Live distros - and once I got HDMI audio properly working (not quite as easy as it could be) had a bit of a play.

Quite impressed with the VDPAU support for H264 - but what's the state of play with de-interlacing?

I've got a lot of native interlaced SD MPEG2 stuff, and some HD H264 stuff. With DXVA de-interlacing in Windows Media Center, Power DVD etc. - this all gets de-interlaced properly (so 50i is converted to 50p with proper motion)

However whatever de-interlacing setting I chose I don't get decent full-frame rate motion.

I tried VDPAU Temporal - and it didn't seem to do anything worth writing home about.

Also - I ticked adjust frame rates in the set-up option - but it doesn't switch between 50Hz and 60Hz when I play 60Hz content - I get 60Hz content with judder (as it defaults to 1920x1080 50Hz)

All advice gratefully received. Has anyone got XBMC doing a decent de-interlace on interlaced content (rather than just unpicking 2:2 or 3:2 progressive sourced stuff)?

Hmm - just done a bit more research that suggests that VDPAU de-interlacing isn't available on <720p MPEG2 - as it doesn't work with the XBMC DVD overlay implementation?

Real pity.

I'll have another look at H264 1080/50i stuff and see how that fairs - I was pretty certain it wasn't de-interlacing properly with Temporal VDPAU de-interlacing.
