Oh, I didn't know that. I have a capable enough system (Athlon II x2 245e). I am using VDPAU because it is there and figured it would be better. Don't even need to de-interlace (one frame* is good enough) as I have an interlaced display. I gave it a quick try this morning and it didn't seem to switch to Full when watching a recording of Gilligan's Island on an HD channel. Is there something else I need to set?
I will likely still want to downconvert programs like this to SD to save space so I will try the script Kris B. linked to when I get a chance.
* this brings up a pet peeve of mine, why does MythTV weave the frames together when you set de-interlacing to none? Weaving is a form of de-interlacing (a very bad one, but it is one) so it is very misleading. IMHO, it should keep the video interlaced If MythTV needs to have the video in a non-interlaced format, it should then use one frame (half size) as that can easily be converted back to an interlaced format without any artifacts, either that or remove the option to have no de-interlacer.
