Can you record a program (i.e., not using LiveTV)? I'm wondering if it's
the same problem I ran into with my ivtv-based tuner (although my symptoms
were not identical to yours). If you're set up to compile your own, could
you try it with backing out commits 3944ca9ad0f8df1a0240c5812e5b3b04431e7eac
and e54b9b6fd635df024f81c1d2f33956996c95c379 ? Reversing those commits
(actually their equivalent in 0.25-fixes) fixed the channel change problem
for me, although nobody seemed to care when I posted about it...
