The rtvtools docs say:

"MPEG-2 files should have the following attributes:

Resolution: any valid MPEG-2 width, 480+ height
Framerate: 23.976, 29.97 and 59.94
Bitrate: 2-8Mpbs CBR/VBR
Audio: 48KHz @ 112-320kbps, MPEG-1 layer II
GOP struct: 1 seq per GOP"

One
It looks like I can convert a file as low as 480 Resolution, 23.976 framerate, 2Mpbs Bitrate, 48KHz @112kbps MPEG and stream it to a ReplayTV via DVA. This correct?

Two
What is the Resolution, Framerate, Bitrate, Audio of a native 'standard' quality RTV MPEG? Can a ReplayTV stream a lower quality MPEG then it can produce (lower than 'standard' quality)?

standard quality replay properties -


Image size: 352x480
Frame rate: 29.97
Data rate: approx 270KB per sec.
Audio: 48000 Hz - 16 bit - stereo

audio rate can not be more than 320kb if i remember right, for any mpg being converted to a replay tv mpg.

audio on all quality settings seems to be the same. for medium quality & high quality, the frame size the replay records at is 720x480. as far as i can tell, the only difference is the data rate change. at medium quality, it's about 540KB per sec - at high quality, it's about 1MB per sec.
