AS far as I'm aware, most if not all of the actual replication takes =20
place outside of the United States.

I still do delivery to clients on DLT tape who then take that to their =20
respective replicator; however, I just completed a fitness DVD being =20
replicated by SF Global Sourcing (sfvideo.com) and they allowed me to =20
deliver layer0 and layer1 (two layers for a DVD9 title) on DVD-R =20
(burned as ISO in Toast).  There was something tricky about the ISO =20
setting in Toast (I had to change a setting to CD-ROM ISO or something =20
like that).

Although, until I see DVD-Video discs in a spindle for that project, =20
I'm keeping a few DLT tapes handy.

If a replicator is accepting a DVD-R with a VIDEO_TS folder for =20
replication, then it's always been my understanding that they are =20
reverse engineering it to get it to being a layer0 file (I forget the =20
file extension that gets appended as this data is usually layed out to =20
DLT tape where you don't see the extension).
