what encoding rate should i use with the hauppauage hd pvr for standard definition and high definition?
im using constant rate of 13.5mb which seems excessive for standard def footage, so what encoding rate should i set for standard def and what should i set for high def... im wanting no loss of quality in either recording,

If you plan to put the SD on a authored DVD, ~10Mb/s should be plenty. HD varies, but maybe ~48Mb/s. I'm going by 'WHAT IS' DVD and Blu-ray to the top left on this page. But I would probably try ~25Mb/s for HD and see how it looks.

I find 6-7mb sufficient for hdtv captures in widescreen to fit on single layer dvdrs. You can punch it up more for dual layer dvdrs. This is for avchd creation of course. I don't have a bluray burner so I do avchd.
I also don't do sd captures on the box because I want actual dvd output when I capture sd material so recording to h264 only means more processing for my sd process.Donatello - The Shredder? Michelangelo - Maybe all that hardware is for making coleslaw? -
" im wanting no loss of quality in either recording, "
it only encodes up to 13.5, i will be reauthoring the hd footage and sd footage to a bluray format, so i should just keep it at 13.5 for the hd's and sd's maybe. hoping someone could help in light of the fact i want no loss of quality at all for future reencoding/authoring. -
You can't have "no loss of quality at all" with the HD PVR. h.264 encoding always loses quality. But HD recorded at 13.5 Mb/s with HD PVR looks very good. 13.5 is overkill for SD -- unless you have very noisy reception.

Other things being equal, the highest bitrate is always the highest quality. But, depending on the nature of the source, you may not see much difference between 13.5 kbps or something lower. A clean digital source with little motion will require a lot less bitrate than a noisy analog source with lots of motion. See the video files in this post for example (the files use Xvid but the principle is the same):

It's really something you have to experiment with for yourself.
