Ah. Any idea what type laser is needed for DVD-R
then?
AFAIK, all of the DVD formats use a red laser for reading and writing.
Apparently the DVD consortium is NOT going to approve a new high-def
format using a blue laser (as proposed by the BluRay companies), but
is instead choosing to use higher compression ratios instead. I already
find the artifacts on current DVD-Video to be somewhat objectionable
(though generally not as bad as the noise on VHS tapes), so I'm not
thrilled about the idea of compressing it even more. While I'm sure
that newer compression technology will be somewhat better for the
same bit rate as MPEG 2, I doubt that it's really four times better.
