Hm - xine? The av7110 driver is for full-featured cards.

The patch will not reduce the number of crashes but it should improve
recovery from a crash...

My way[tm]:
I prefer to test multiple driver versions or cvs snapshots without
overwriting the modules in /lib/modules/...

So I _never_ use 'make install'. My way[tm]:
- cd v4l-dvb/v4l
- make
- load driver using 'make insmod' or some other script...

You may edit insmod.sh to load only the modules you need.
Or use a script of your own.

Why the hell does a simple 'make' in the v4l-dvb main directory execute
as 'make install' in the v4l-dvb/v4l dir?

Imho install should _never_ happen automatically.
- make in the main dir should do a make in v4l
- make install in the main dir should do a make install in v4l.

Just my 2 cents.
