OK, good to hear. This is what I am trying to do.

With the msp3400.ko renamed as in Jarrod's guide, I will get sound (from
the sound card) and video from the PVR-250. I get video (but no sound
from the card) from the PVR-350. When the msp3400.ko is left as is, I
get sound and video from the PVR-350 but only video from the PVR-250 and
nothing from the sound card.

Yes, but I don't get it as part of the video stream either.

Thanks for details on your modprobe.conf. Mine if very similar although
I don't have the tuner-ivtv alias. I will try configuring mine them
same and see what happens. If there is no joy, than it looks like I
need to look more into configuring ivtv and this may not be the best
list for getting answers.
Thanks again for the info.
