That was me screwing up a bit, both backends report the encoder as not
recording and this is just after starting the backends.

prints when i try to start livetv

Yes that was just to verify that it was working.

What i mean is that i make switch so that the dvb backend is master and the
pvr-x50 is slave, if i start the dvb backend first i can use all tv dvb
channels but if i start the slave with the pvr-x50 cards and the first
channel it jumps to when entering livetv is a x50 channel i will never be
able to go to a dvb channel it will just switch back to the previous channel
after trying to switch.

Is anyone else here successfully using a similar configuration ?
