Its on the official site and in the official docs as well. No betamax,

Ouch. Very not good... Try launching mythfrontend w/gdb and see if that

I still intend to set mine up before too long here... (I've said that
before though -- my pcHDTV card has sat unused for months now -- but my
dev box is back up and running with it in it now, so there's hope!)...
