| 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. 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.

Every copy is the same as the original. Also, it's assumed that the data structure is compliant with DVD-Video specifications. Usually, the minimum run is 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 folder) without going to replication. To play this in a DVD-Video player or Blu-Ray player, you would typically burn the VIDEO_TS data to a DVD-R, DVD+R, DVD_R DL, etc. As long as the player can read the media you've used, the content should play as expected. These are "burned' or "one offs'. In a computer, this can play directly from a hard drive. > > Apple Compressor has great MPEG2 settings as long as you use the ones that have "best" in the name.
