[mythtv-users] Can't watch firewire source live, but it records fine.

[Christopher Meredith]

Okay, I have an SA3250HD cable box and I've been using it with
firewire and MythTV for several months. It is very stable, due in
large part to using this channel changing wrapper script:

http://bentonroberts.com/personal/media-server/code/mySA3250change.sh/view

I have MythTV configured to use that script as the channel changer,
and it works perfectly for scheduled recordings. The problem is, I
can't watch my firewire channels through the live TV function. MythTV
executes the channel changer just fine, but the screen turns black and
I get repetitive error messages streaming up my frontend console. The
look like this:

This is a Mythbuntu machine and I'm using the 0.21-fixes VDPAU
backport repo. That said, I've had the exact same problem using the
"stock" Ubuntu builds, even before I started using VDPAU. Also, this
is a unified backend/frontend machine. There are no remote/slave
backends or anything.

If anyone can help me troubleshoot this, I'd much appreciate it. Thanks!
