[mythtv] Mythtv and kernel 2.6.25

Mythtv failing to bind indicates that something else is using the port.  Are
there multiple instances of Mythtv-backend running?

I notice the autodetection doesn't find the tuner, are you using
composite/svideo input or the tuner?

Do these same lines exist in 2.6.25?

You may want to make sure you are accessing the device throught the same
pathway in the two kernels (v4l2 vs v4l1 or dvb bttv support).

It may be a good idea to look at mplayer -v to see if there are any
differences in accessing the device.

Just a few thoughts to explore

Good luck,

-Dan
