| 4-hour DVD / 30-min SVCD  (record mpeg2 2200bps, no transcoding)
| Quick 1-hour SVCD	  (record mpeg2 1100bps, no transcoding)
| 1-hour SVCD		  (record mpeg2 4500bps, transcode to mpeg2 1100bps)
| MPEG4 HQ		  (record mpeg2 4500bps, transcode to mpeg4 2200bps)
| MPEG4 LQ		  (record mpeg2 4500bps, transcode to mpeg4 1100bps)

Do the bitrates in the profiles actually work for hardware encoding
(PVR-250/350) at this time? I had thought that they had no effect on the
encoding settings for the PVR cards. I've been using my own scripts to
set the bitrates because I didn't see any effect from changing the
settings in the profiles. I wonder what I did wrong.

| is that something like "record mpeg2 4500bps" or "transcode to mpeg4
| 2200bps" would be a "profile", whereas grouping them together like
| I've done above to create "2-hour DVD" would be a "profile group".
| I presume that's wrong, but is what I want possible?
