[mythtv-users] HVR4000 woes

Well, as a matter of fact, if you build the vanilla v4l-dvb-20100517
repository and install this, this breaks the TT-3200 and it won't load the
drivers for it at all.

At the time it never occurred to me to see what would happen if I just tried
to use the HVR 4000 alone, so intent was I on getting my TT-3200 back.

I could just remove the hack that allows the TT-3200 to load and that would
disable it completely. I'd have to add my cards back into myth but it would
be an interesting experiment.

Lots to play with ...
