I believe it's called scanfw 
(http://ubuntuforums.org/showthread.php?t=795378).  I've used it before 
but not in a while.  I'll have to give it another try and see what I 
have as far as 5C channels are concerned.  What stinks is that I only 
have a few channels that I even care about recording over the firewire: 
namely the HD feeds of USA and SciFi.  I currently record WWE wrestling 
on the SD feeds but getting them on HD would be great.

I guess I may need to step up to an HD-PVR.  This may sound dense, but 
the feed coming from the cable box over Component Video will be HD, 
right?  Just in the clear, correct?  I was going to wait until 0.22 
comes out, but I guess I could investigate upgrading to trunk to get 
HD-PVR support.  I feel like I may be a bit too far behind the curve to 
do that however.  I know how to compile from source, but all of the 
little "gotchas" such as what to pass to the configure script, etc. 
could really be painful to go through.

I can compile on my main box without affecting the current running 
version right?  As long as I don't do a "make install" I should be fine, 
right?  I have Mythbuntu 8.10 x86_64, so are there some pre-built 
packages against 0.21 that have the HD-PVR support built in?
