I had a DCH-3200 from Comcast and had all sorts of trouble with it
over firewire.  I was never able to get it to work reliably.  I went
to Verizon FiOS for a few months, then switched back to Comcast and
got another DCH-3200.  This one has worked flawlessly, with the same
MythTV backend hardware.  I have no idea what the difference is.

For Comcast, I can't recommend the HD HomeRun Prime highly enough.  I
now only rely on the firewire connection when I have at least three
other recordings going.
