XV support on the PVR350 is coming along well now, and should (and

The MythTV docs (which do seem to be rather out of date with regards
to the PVRx50) state that frame buffer based output on the PVR350
puts quite a load on the CPU. Is this still true, and if so is it
high enough that I might have trouble running MAME or snes9x?
The MythTV docs specify information regarding the current "stable"
release of IvyTV--version 0.1.9. All the information they give is
completely correct--framebuffer-based output takes a lot of CPU--but if
you choose to use the "unstable" versions of IvyTV--version
0.2.0-rc3(whatever) or 0.3.6(whatever), you may (should) use the Xv
support that John added. If you're using Xv support, video on the
PVR-350 is basically as processor-intensive as video on a "real" video
card using Xv support (but takes more processor than using XvMC--which
you should only need for high-def, which the PVR-350 can't do).
However, OpenGL is not (and cannot be) supported on the PVR-350 (since
it has no 3D acceleration in the hardware).
