If they don't give you a firm specifications or just refer to "files" your DVD will most likely turned out to be a coaster If the replicator accept files on external hard drive or data DVD ask exactly what format should be the files, some smart and knowledgeable replicators will accept pre-mastered DDP files stored on hard drive and then create the master from them.
Sending DVD-R for DVD-5 is inexpensive and great time saver, but you have to be sure you don't end up with replicated DVD-R If the replicator accepts DVD as a source ask exactly what they do with it - do they just copy the DVD-R as it is or they quickly remaster it to DVD-Video. To avoid the problems that are described below, try to get as much info as you can By using DVD-R as a source, the replicators are in normally addressing creating of the DVD-ROM with data, not a DVD-Video, which the manager personnel you probably deal with may not know. For small releases that may not be a big problem, but there are still few players out there that will have trouble playing DVD-R even if it is molded. However if you don't have special Authoring DVD-R drive (cost about $4000) what you will get back could be just an exact copy of your DVD-R a molded DVD-R with 2048 bytes per sector not a true DVD-Video. The DLT tape itself must be type III or type IV, no compression, recorded at a maximum 20 Gb density.įor DVD-5 the replicator may say they will accept burned DVD-R as a source. So obviously you would start thinking about bringing the files on recorded DVD or by other means, which is unfortunately a first step towards troubles.ĭLT tapes should be written to follow the DDP (disc description protocol) 2.0 spec. You can't go to a computer store and buy new one. One of the most interesting paradox is that the DLT drives for the format the replicator can actually accept is no longer manufactured. If you ask what DLT tape, as there are many different sizes or formats these days, they will mostly give you answer that would be "uhm, a normal DLT tape".
What the replicator will tell you is to bring the DVD files on DLT tape or on DVD. It seldom works this way.ĭespite it is 20 years from the time the DVD specifications were approved, replicating DVD's is still a black magic where the magicians knows a very little about it. No matter how some people try to make this step look easy, the replication is the part where most of us loose the control over the DVD and simply trust the replicator to do everything correctly. Replicating the DVD - Down the rabbit hole I am quite confident all is correct and I didn't make any error in VM commands or playlists.
Ok, so right now, I have my DVD compiled on hard-drive and I tested it also on few DVD players.
