Some weeks ago a posted a patch for the Pinnacle PCTV Sat driver
which changed the (broken) relay[1] handling code - it wasn't possible
to use the video-in connector and the DVB receiver at the same time.

With the patch that was fixed but I had to change both drivers, bttv
(don't touch the relay) and dvb (activate the relay at the moment the
frontend device is opened).  I've heard the bttv maintainer has picked
up the bttv part[2] but I've no idea whether the dvb part has ever made
it into cvs.  When 2.6.15 is out I'll update my system and will make a
new patch if necessary.

[1] The relay switches the IF-in signal either to the IF-out connector
(off state) or the receiver (on-state).

[2] The change concerning the relay handling is the removal of the two
lines .gpiomask=0x01 and .audiomux={0,0,0,0,1} in the bttv_tvcards
