Hi, I recently got a rather budget priced DVD recorder,
(Magnavox msr90d6).

Lots of DVD recorders are being closed out. Most have NTSC tuners which will
be at least partially toast within the year.  HDTV fever is upon us.

All the manual says is that the audio
records at 48kHZ and the 'compression format' is Dolby
Digital.

48 KHz sampling is a video thing.  I doubt that this thing makes recordings
with audio in any format but MPEG.

The 'compression' part doesn't sound too
promising but... will this record the audio portion at CD
quality level, or something significantly below?

Even it it did record Dolby Digital, Dolby Digital is rather highly
compressed as compared to CD quality. It is a very old format, and is
probably not even as effective at a given bitrate, as MP3.

 Also, does the highest speed, at 1 hour per DVD, record the
audio track better than any of the slower speeds, or
would 2 hours per DVD record as well?

I would expect that 1 and 2 hour mode use similar amounts of compression,
and things go downhill for the longer modes.

That all said, the sound that comes with video recorded in 1 or 2 hour mode
is not that bad.

see Dolby Digital or AC-3
