I've got a Hauppauge card and an Nvidia graphics card and for quite a while now I've a picture problem watching television (via Kaffeine dvb). Pixels have been flickering and changing.
I'm using opensuse 11.2 (64 bit), Nvidia 173.14.25 and I recently decided to try the new kernel 2.6.33.x. Not for the TV, I assumed that was my aerial.
Well, I'm having no problems with the new kernel and my TV picture turns out to be perfect now.
I thought this might be useful for others to know if they haven't already tried it.
