I have found in practice that touching anything to do with video/TV by using the 
Control Centre is usually counterproductive. (It's brilliant for most other 
purposes, though.)

I tend to pore over the files in /etc looking for things which might be "out of 
place". Unfortunately the Mandriva installer does some dumb things which were 
relevant to previous package versions, and not been kept properly updated. I 
will add/update the wiki when I can, but that won't be till the week after next now.

Your files look OK. I haven't had to rmmod anything; but I'm still using ivtv 
0.7.0. I didn't have any problem with cat /dev/video0 > file.mpg. Have you used 
the tools to make sure you are tuned to a real channel?

I'm sorry I can't be of much more assistance here. For my combination, things 
have mostly "just worked". I have had more trouble on the DVB-T side.
