To flush this one out a little bit...

A DVD-Video disc is replicated (literally stamped from a glass master =20
or gold disc master in a dust free environment).  Every copy is the =20
same as the original.  Also, it's assumed that the data structure is =20
compliant with DVD-Video specifications.  Usually, the minimum run is =20
2,000 discs.  There's always an "overun", so you get more than 2,000.

However, you can build the DVD-Video data structure (the VIDEO_TS =20
folder) without going to replication.  To play this in a DVD-Video =20
player or Blu-Ray player, you would typically burn the VIDEO_TS data =20
to a DVD-R, DVD+R, DVD_R DL, etc.  As long as the player can read the =20
media you've used, the content should play as expected.  These are =20
"burned' or "one offs'.  In a computer, this can play directly from a =20
hard drive.

Apple Compressor has great MPEG2 settings as long as you use the ones =20
that have "best" in the name.  Some encode MPEG2 in DVD Studio Pro =20
which ironically does not have a preset that favors image quality.

And... if you care about image quality, 150 minutes is the most you =20
can cram onto one layer (a DVD5 if you're replicating).

Fun stuff, no?
