I figured out that the difference between channels was the resolution which
through the profile determined if XvMC was enabled. With CPU++ (no XvMC)
there are no blank screens but the picture is no good because my CPU must
have XvMC.
XvMC worked great under 7.10 but I could not repeat the build after my
disasterious upgrade. It was suggested here that I use 8.04 which looks
great, but without XvMC is no good. I need to troubleshoot XvMC under
Mythbuntu 8.04.
I will work on it but it sure looks like a bug to me as my system worked
with XvMC under 7.10.
Anyone care to enlighten me about what is going on?
