Comment 1 for bug 525703

Devin Heitmueller posted the following answer on the linux-media mail list which fixes the problem for me:

There were some changes made in the 2.6.33 mainline kernel which were
incompatible with the v4l-dvb tree (and the saa7164 tree on the
kernellabs hg is based off of a version of v4l-dvb that is several
months old).

The issue should have been fixed relatively recently in the v4l-dvb
trunk (which *does* contain pretty much all the hvr-2200 fixes).

I would recommend you do an "hg clone http://linuxtv.org/hg/v4l-dvb"
and do a compile and see if it works. If it doesn't then post a
reply. But to be clear, this has nothing to do with the HVR-2200
support in particular.
