It's set to CPU+ - I think I tweaked it a little from the original so
for the res <= 720x576 & res >0x0 it's set to 'standard' decode, xv-blit
render with softblend OSD and it's kernel deinterlacing or linear blend
as the fallback. CPU usage is less than 40% - this setup worked fine
before hardy so it should not be a CPU issue.
Having you mention looking at the playback profiles I tried the opengl
renderer and I get video playback - almost stutter free, although the
CPU is approaching 100%. I therefore presume that something important is
different in Hardy with regard to the way video works in X. It would be
nice to have working video and not 100% CPU.
Thanks for the help so far :-)
