I'd need three coax cables that length to do it with the composite
signals (L R and Video). This is accomplished with one cable, no
noticable loss of picture quality

It's about 25 feet or so

True. But then I'd need to buy an amplifier :-P I want to make it work
with what I've got for now - eventually I'll just be putting a PC next
to the TV and it'll all be fine, but for now, I need a long cable so I
can use my desktop.

Yeah, it's definitely a broken cablebox. I actually have two Svideo to
RCA adapters, but I can't find one of them (I would need to convert it
to RCA from Svideo and back to Svideo again at the input of the
capture card.

I did eventually get it to work - I set up the input to be tuner0, but
to use the external channel program to change channels. Not sure what
will happen if I reboot, though, since I think the only reason it was
on channel 3 was because one of the times I got it to use the tuner, I
tuned in to channel 3.

Is there maybe an external program for tuning the analog tuner like
there is for connecting to the external cable boxes?
