Keep these lines. Er, wait a sec... You said you have just a PVR-350... Then 
yank the 81-1 line, that would be for a second card...

Remove all four of these lines. I'm assuming you're not using the 350's tv 
output, judging by the lack of ivtv-fb anywhere in your modprobe.conf.

Aren't you in NTSC land? This is bad. Removing all that excess junk from 
modprobe.conf should let this get auto-detected properly.

Yank all that stuff, see if things clear up, then come back to this if 
problems still exist.

Hm... You might not have the merged msp3400 installed, and the old stock 
msp3400 definitely won't work, so you may have to manually modprobe 
msp3400-ivtv for now... See the ivtv-dev list post from Axel re: recent 
msp3400 changes...

Screw it, here's what Axel said:

"There are now new rpms for both v4l and ivtv out:

o today's v4l has fresh changes in the msp3400 code, please give it a
o the ivtv rpms ship again with the msp3400, but it's been renamed to
  msp3400-ivtv (in order to coexist with the msp3400 from v4l).

If the default config does not work (which will use v4l's msp3400),
please try to

       rmmod msp3400
       modprobe msp3400-ivtv

and check again. If there is improvement it is due to differences in
v4l's vs ivtv's msp3400 code, and it would be good to identify these."

I'm recording the debates, I'll watch 'em later (still at work anyhow). :-)

In your lsmod output, no msp3400 at all... Definitely try modprobing 
msp3400-ivtv. The i2c errors you're seeing may be a result of no msp3400 
module loaded.

Damn skippy. Been hacking my friend's TiVo for him, first I've touched one. He 
thinks its cool as hell. I think its pretty wimpy. :-)
