</div> "mpeg-4 AVC Hardware encoder" is the one you want to control the HD-PVR<br>

says<br>
You can set the bitrate for the HD-PVR by going into Recording<br>
Profiles, and editing the profiles associated with HD-PVR encoders.<br>
These recording profiles have bitrate settings for low (480i/p),<br>
medium (720p), and high (1080i) resolution material, allowing you to<br>
set appropriate bitrates based upon the resolution of the material. If<br>
the max bitrate is set lower than the average bitrate, the result is<br>
CBR (Constant Bit Rate) at the rate specified by the average slider.<br>
If you want VBR (Variable Bit Rate), set the max slider to maximum,<br>
and then use the average slider to achieve the desired bitrate.<br></blockquote><div><br>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.<br>
