[mythtv-users] Mythtv, nvidia and tvout

[huffman at graze.net]

Based on what I've been reading, I may first play around with the modes and see
if I can get a mode that does not require scaling.  From what I'm reading, it
seems that the problem has more to do w/ the card being forced to scale up or
down....since it sounds like the TVOut already outputs an interlaced signal.  

I guess if there was some way to pass the interlaced signal that the PVR-250
records straight through (w/o deinterlacing, scaling, and then
re-interlacing...or whatever is happening), it would be perfect.  Obviously this
isn't possible since Myth does things like Add the OSD on top of it and other
graphical modifications to the original recording.

until my experience yesterday, this was not confirmed.  I may have other
problems, so I still do not know if XvMC offers any hope or not.  I would be
interested to hear if you are successful with this mode, or any other method to
smooth the playback...
