[mythtv-users] Playback problem on M10k - Unable to create XvMC Blocks

[Brian Webb]

Rob,

I have a very similar setup, and I've been trying to get it working
for weeks.  Currently I'm seeing the same message that you're seeing. 
My latest theory is that the ATPMS myth rpms are not built with VIA
XvMC compiled in.  The spec file appears to default it to compile
without VIA XvMC, and I don't know how to tell how the binary rpms
were compiled.  Can anybody confirm this?
