[mythtv-users] problems with live TV (at program boundary)

Hi,
I am running mythtv with backend and frontend on the same machine using 
firewire input. Everything works great except for a weird problem with Live TV 
when a TV program ends. Myth attempts to switch to the following program on 
the same channel and then quits. The frontend gives me "Error opening switch 
program buffer". In the meantime, mythbackend creates two mpg files in the 
recorinds directory however, the file sizes remain zero.

In the log I see messages like 
2010-09-24 00:00:06.416 LFireDev(001E5AFFFEACA5D5), Warning: No Input in 1050 
msec...

2010-09-24 00:00:07.269 LFireDev(001E5AFFFEACA5D5): SignalReset(6->7): 
Updating device \
list -- end

But also messages to the effect that "external tuner program exited with no 
errors" (in attempts to fix it I tried used firewire priming scripts to change 
the program).

If, instead, the next program is scheduled for recording (instead of me simply 
watching it as live TV), mythbackend switches without any problem and allows 
me to continue watching.

Any help with fixing this would be appreciated.

Thanks,
Yuri
