Summary: Channels fuzzy ATI TV PCI, TVTime & FC2

Initial Comment:
I'm hoping somneone's come across this already.  I
thought FC2 isn't picking up the right tuner type
anymore but "dmesg | grep tuner" tells me that bttv is
using tuner type=2, which is correct or my card (card=63).

Ever since I upgraded from Fedora Core 1  to Fedora
Core 2, my ATI TV Wonder PCI / tvtime combination
doesn't seem to give me a clean TV screen - al the
channels are VERY fuzzy.  Very scrambled, as if I don't
have the right frequency table, but I'm just guessing.

Has anyone else had problems going from 2.4.x to 2.6.x?
 (I'm only assuming that it's due to the kernel upgrade
- could be anything).

I know I have the right tuner / card setting in my
modprobe.conf file as follows:

alias char-major-81-0 bttv
options bttv tuner=2

since it worked under FC1 and kernel 2.4.x.  I'm in
Toronto / Canada and have Rogers Analog service.  I'm
attaching a png of what the channels look like now.

Does this look familiar to anyone? HELP!!

Sure thing.  Not sure how to disable XDS and CC encoding
durig runtime though.  Is the only way a recompile?  I
googled for this but couldn't find anything useful.

OK, first is my /etc/modprobe.conf

alias char-major-81-* videodev
alias char-major-81-0 bttv
options bttv tuner=2
alias char-major-89-* i2c-dev
# options i2c-core i2c_debug=1
# options i2c-algo-bit bit_test=1
alias char-major-81 bttv

Also my dmesg output...I did   %dmesg | egrep
"msp|bttv|tuner|video" 
to make it smaller.  IF you like to see the entire thing,
jsut let me know and I'll be happy to post it all.

This sounds pretty strange.  Can you post the full output of
'dmesg' on your system?  I would like to see how bttv was
configured.  Also, can you make sure you have disabled XDS
and CC decoding?  There are bugs in the VBI code of bttv
under 2.6 kernels.
