If it works fine for you, don't fix it. If it gets to be a pain,
however, switching will give you some advantages:
- XvMC may be able to minimize processor impact of video decoding.
Probably not AS good as the PVR-350, but not nearly as bad as no
acceleration. I believe the 7xxx series supports XvMC.
- You will gain OpenGL and probably have significantly faster menu navigation.
- You will be able to use other programs on your MythTV: DVD players,
ability to play non-mpeg video without being jumpy. Games, for
- You'll be able to actually fast-forward, which is missing from the
PVR-350 support. (skipping works, but anything above 3x FF/RW will not
work with the PVR-350)
I used a PVR-350 for a few years. I stopped using the TV-out because
my new video card had TV support, and have been impressed by the
OpenGL. But my 8600 does not support XvMC, so I lose a little on the
processor usage front.
