If I stop mythtv and restart it again all is well.  Similarly tzap; dvbstream | mplayer works just fine.  It's just mythtv that seems to have the problem.  I guess it's possible that PCI latencies might need looking at - next on my list - but I'm doubtful that is the problem in this case.

I've been using a nova-t for some time now. I occasionally see the
symptoms you describe but not consistently. It usually occurs  when I
switch from one mux to another e.g BBC1->ITV2. Exiting live tv and
reentering it seems to clear the problem. I'm not sure what this tells
us though :-|

I might even have seen the problem on initial startup but I'm not
convinced about this. BTW I'm using kernel 2.6.5 so I guess a kernel
upgrade may not help.

Other people have reported similar problems to the list.
