No, it's hanging. It should either be printing an error message saying why it
couldn't setup the Xv stuff, or saying what Xv port it was using after it
sucessfully set it up. It's not doing either, so it's hanging =)
You said xawtv only works when you use the -noxv switch? I assume it hangs as

Nope, there's not. Well, if you record an entire program and then go to the
'Watch a Recording' screen in mythfrontend, it'll play a little preview video
of the file, without sound..
