Higher bitrate means bigger files, which means fewer hours of TV fit on 
your system.  With a hardware encoder (i.e. PVR-x50/PVR-500), there's 
(practically) no other effect on system resources.

Note, though, that with the PVR-x50's/500's, having an average bitrate 
over 6000kbps is probably a waste.  As a matter of fact, you're likely 
to hit the electronics' quality ceiling by 4500kbps or so (assuming a 
good quality input signal).  Just make sure you have a reasonable 
maximum bitrate (about 133% the average bitrate).  The default for PVR's 
is 4500kbps average and 6000kbps max.

Oh, and if the assumption of a good quality input signal is invalid, 
fixing the signal will do far more good than changing the bitrate.
