Yes, I did commit a patch to do that. However, that doesn't work for
H.264, only MPEG2 (sadly). As I record more TV per day than there are
hours of the day (typically), the commflagging must keep up. I
actually run 4 commflags in parallel, and at high CPU profile (not
niced, and tops out at 200% each for me). This box serves me very
very well. The previous machine (Pentium-D 2.6GHz (I think)) was far
far too slow for my liking and couldn't keep up with my load.

There are CableCard options coming out soon, but still only useful for
the same channels that ClearQAM would give you. The HDPVR is able to
record off component outputs from your cable box or satellite box...
in lovely HD. :)

Then get DirecTV.

We do not promote torrent boxes here. Piracy is not appreciated here...
