I am also having the same problems, but with Fedora 11 x86-64. On Fedora 10,
this configuration worked fine, but when I upgraded to F11 in August, that
is when my problems started. Clearly, something is wrong with MythTV, as
this does not appear to be distribution specific. Like you, I can watch TV
on Kaffeine, but Mythtv just refuses to do anything. ScanDVB works, as does
tzap.
