[mythtv-users] PVR-350 cannot watch live tv until after a scheduled
recording

Hey folks,
I have MythTV 0.18 (finally) running, but am hitting one very frustrating
problem: I cannot watch live tv until after a scheduled recording has
occurred. If I try "Watch TV" before mythbackend has recorded something,
it goes to channel 4 for about 10 seconds before dumping me to an error
screen saying "Error was encountered while displaying video" with only a
single button, "Return to Menu". During those 10 seconds, mythfrontend is
completely unresponsive. However, after the first scheduled recording,
everything is fine until I have to reboot the system (usually because
mythweb crashes mythbackend and KDE messes up access to /dev/dsp,
requiring reboot).
I have looked through the list archives and not found anything... anyone
have any ideas? It sounds to me like mythbackend uses a different routine
to initialize the card for scheduled recordings from the one it uses for
live tv. I am sure I am just missing some config option, but for the life
of me I can't find it.
Thanks,
john
