replicator suddenly wants video-dvd as masters instead ddp2.0 as agreed before

hello,

this is a huge problem. The replicator (USA) just emailed and now suddenly needs to have Video-DVD as masters. (In my first email to them I made clear that replicating from video-dvd masters is not an option!) (pressing from video-dvd is just the worst way possible)

the replicators website has no specifications online. So i called them in advance to make sure they can handle DDP2.0

As i wished they also confirmed me that by email before i sent out the masters !

It's a DVD9 ddp2.0 built (layer0 and layer1) burned (UDF system) onto two Sony DVD-R (we also sent copies of the masters as well)

The masters were tested in advance by a professional with DVDafteredit mastering edition!!! The masters and the copies that we've sent out are absolutely 100% O.K.
We know a lot about DVD authoring and the masters are fine but they just can't handle ddp as promised. This is very unprofessional.

(moreover the other replicator in germany had no problems replicating from the same ddp2.0 masters !)

here is the original email they just have sent:
--------------------
The stamper house said that the final master needs to be in TS VIDEO &
TS AUDIO. When I put the Final masters into a computer, the files that
should come up are the TS Video Files & TS Audio Files.
---------------------

As it seams they don't even know that the ddp masters holds the original VIDEO_TS and AUDIO_TS folders within and how to extract them properly...
Burning ddp2.0 onto dvd-r is just the same format as exporting ddp2.0 to DLT tapes (which they also accepts how they claimed by email)

What do you think about the situation? We could actually sue them because we can't meet our official release date before xmas because of them.

Do I now have to tell them how to do their job or should we search for a new replicator (which could take some time that we don't actually have right now)

I will definitely not send them DVD-Video masters for replication! this is just stupid!

hope for your quick help what we should do now.
best regards,
Silvio
