   No no just a PC to record TV, not making a set top box or anything.

   When I said "build a box" I didn't mean actually physically build 
one, I just mean to configure a linux box specifically for nvrec.

   Well, TV shows, so... an hour? Maybe two?

   But I would like to be able to use more than one card at a time.

   I have that working system I talked about before, kernel 2.4.26, 
ffmpeg 0.4.9-pre1, nvrec-cvs current, and it works fine and does more 
than one show at a time using two cards. But I would like to upgrade 
that box.

   I have some other unrelated issues on it that would be helped if I 
upgraded it. The box does a few other things (like X10 control).

   However, the nvrec/bttv system seems a little finnicky. I seem to 
need to try a lot of versions and compiles and tests to get a working combo.

   I tried upgrading it to kernel 2.6.11, and it works for one card but 
if I try to start recording from the second card, it never makes the 
output file... it just pauses for a few seconds then starts spitting out 
that "No place to put data - discarding 0" message until stopped.

   The output file isn't even created, which seems strange.

   I would also like to use v4l2 (so I can monitor with xawtv while it's 
recording), but if I attempt to build for v4l2 it seems to try doing a 
v4l1 core init anyways and then fails with invalid argument on set window.

   Rather than send a list of complaints to this list, I figure I would 
build the box freshly using a new deployment and whatever versions of 
kernel/bttv/ffmpeg/nvrec are known to work together well.
