[pvrusb2] Audio video syncro using kaffeine.

[xavier.gnata@free.fr]

Hi,

Having a mostly perfect driver is great but having a compatible TV application
of this century is also great ;)

xawtv4 is almost dead.

As mentioned on this list, kaffeine fifo:/dev/video0#demux:mpeg does the job.
I'm fine with it because kaffeine devel is very active (it is fully part of kde
:))

The only problem is that audio is not sync to video using kaffeine (sound is
always a bit late).

I have no clue if it's kaffeine related or if it can be simply solved seting a
kaffeine option.

Xavier.
