What have people found to be best?  I'd be interested to know if people use
VBR or CBR and what bitrates for each profile.  I've noticed a 1hr show at
1080i is taking close to 6GB.  That show looks great when viewed and I'm not
low on disk space, but I'm just wondering if it's a waste.  I think I'm
using the default profiles.
