Good to know - I'm not trying the impossible!

Already done that.

I was somewhat unclear - I meant I've tried both versions, not at the same 
time :)


I've since made some progress. Using envy I uninstalled the drivers 
completely, rebooted, installed the 169 drivers and rebooted. Now xine works 
fine and you can really see the difference. However Myth gives:

I checked the Xorg.0.log and the XVideo & XVideo-MotionCompensation extensions 
are being loaded (and of course xine works as well).

I guess this narrows it down to mythfrontend problems. I currently on 
mythbuntu weekly's, I wonder if I should drop back to backports (groan).

Thanks
