If I was planning to use only 1 tuner I would take the s-video from the
receiver and
plug it into the tv tuner card, but my question is does the receiver output 1
or 2
channels? I guess I can find out by trying to use Picture in Picture (I will do
this
when I get home in a couple of days)

This card only has an encoder then not a decoder. No need to decode if it will
not
output anything, is that a good assumption?

I will keep both of these suggestions in mind, thanks. Was it difficult to get
this VIA
motherboard to work? I heard about problems with VIA chipsets and MythTV.
Is the SP130000 well supported in linux?

That helps, thanks. Is this for 720x480?

You are using 30% CPU even when you have a SP130000? (perhaps this is just
acceleration
and not full decoding)
