I think the OHCI 1.0 versus 1.1 issue is only a problem with the new
firewire stack (see
https://bugzilla.redhat.com/show_bug.cgi?id=Juju_OHCI_1.0), which isn't
supported at all by myth yet.

I too am having similar problems, and filed a ticket as it causes my
backend to crash after recording an empty file:


My guess (and I'm no expert, so I'm probably way off) is that the STB is
messing with the PAT/PMT that makes mythtv an angry mythtv.
