Most DVD replication plants will run a minimum of 1,000 DVD or BluRay =
these days. Some of the really big places won't, but it's a common job =
for the smaller ones. I do it all the time, and sometimes we'll even do =
an order for 500 but that's actually leaving half the 1,000 run of discs =
on a spindle and charging the client for the whole 1,000 less packaging =
and assembly. That still comes out cheaper than duplicating 500 discs in =
a duplicator tower and the client has the option of using the unpackaged =
ones later or handing them out as promotional copies. The overages =
aren't usually on the disc side, but on the printer who makes the =
covers. Those guys do a standard 10% overrun on everything no matter how =
much you beg them not to. Then most DVD factories just make some extra =
discs to fill the packages.=20
I don't think I've ever seen the word "great" in the same sentence as =
Compressor and MPEG2 before. Of course it's all subjective, but in my =
opinion at a high enough bit rate Compressor's MPEG2 encodes are =
passable, but lower that rate and the macro blocks start to show up =
fairly quickly. I think you'd really see it in this encode at 4.1mbps.
