[mythtv] Encoder not initializing - static while watching live tv

I'm only getting static while watching live tv. It appears my encoder is
not initializing cleanly. Originally I thought the encoder card was
failing but I confirmed it's working o.k. by trying it in a windows box.
Live tv worked after putting it back in my myth box for a short time but
failed after changing the channel. I can playback old shows recorded
before I started having problems.
Hardware:
MSI 651M motherboard
onboard SIS 650 video
onboard audio (uses AC97 codec)
Hauppauge 350 capture card
Software:
FC3, kernel 2.6.10-1.770_FC3
My modprobe.conf file has the following:
alias char-major-61 lirc_i2c
install lirc_i2c /sbin/modprobe ivtv; /sbin/modprobe --ignore-install
lirc_i2c
alias char-major-81 videodev
alias char-major-81-0 ivtv
alias tveeprom tveeprom-ivtv
alias msp3400 msp3400-ivtv
install ivtv /sbin/modprobe --ignore-install ivtv; /sbin/modprobe
ivtv-fb

Note: I had an nvidia card in this system but took it out. Everything was
fine after I removed the card and used the bult-in video card.
