I am seeing pretty much the identical problem.  I have a DCX3200, and my
HD-PVR goes unstable if I change channels with the IR blaster.  It records
the first show, and then, after that, all recording fail.  If I turn off
channel changes (which I've been doing by removing module lirc_zilog, not
by removing the channel change script from the setup menu), it records
without incident.  Too bad the STB is delivering the wrong content :(

Anyway, I don't have a firewire card yet (got one in the mail), but I was
hopeful this problem might be strictly related to the IR channel changer.
 Now, I'm not so sure.  Could this be a problem with this particular STB?
 Maybe I'll swap this DCX3200 out for the older more clunky Motorola (6xxx,
I think).
