Dual Layer issue

Question

Okay,
I have created a DVD and ran all tests and passed. I transcoded for the 8.5 Dual layer disc and it burned and worked great. I ran out of DL and went and pruchased more. I wasn't able to reburn the project for a few days...had to modify and work and well I was busy. Anyway...now all of a sudden Encore2.0 doesn't recognize my DL discs...when I build project...the option to actual start writing the disc is not one that I can select. Suggestions?

Mike.
This is my opinion, arrived at after talking extensively with my preferred replication company.
Others may be different.
When you write a DVD-Video disc, you're making a very specialised piece of software where every error is critical & may result in an unplayable master, or worse still a master with errors.
Written media is also much less reflective compared to pressed media. This means that the players error correction has to work even harder.
Dual Layer discs have much reduced reflectivity from the inner layer. Obviously because it has to focus
i through
the upper layer to read the data.
The first thing the factory are going to do when they recieve your master on DVD-R as a DVD-Video movie is turn it into a DDP image anyway, so that they can make the Glass Master and stampers. So why not take that step yourself, and send them a DDP image - it's what you write when you make a DLT tape. Best of all, it has it's own internal error correction (I think - but may be mistaken - that it uses CRC error correction) so the integrity of your data is guaranteed. You can even write this data back to HDD (even off a DLT tape) and makea playable disc from it, to confirm that your master is good (if you can be bothered or don't trust the method) before you send it.
Most serious replication companies would prefer (Warners US certainly do, (and recently, I had to deliver to Warners and they refused anything
i but
the CMF-DVD!) as do most record labels/movie companies) you to send them one of the following
i along with a reference playable disc:
1 - DLT tapes, One per layer. Type III or III XT usually preferred, although most can read the larger type IV tapes. The type III and III XT are universally readable).
2 - CMF-DVD, One per layer.
3 - DDP-DVD, One per layer. (This is getting rarer these days, as most go for the CMF-DVD as it's a newer version of the Spec).
Now it's the cynical bit.
IMHO, DVD-R as a DVD Movie is usually accepted because sadly there are a lot of authoring houses out there who have absolutely no idea how to deliver a properly formatted master. It's a desperation thing, as you would not have found a single one 5 years ago who would accept anything other than a DLT. They have had to go this route as I suspect they were getting fed up with being made to look like the Bad Guy all the time rejecting substandard masters. So they will - usually reluctantly, but if you ask them outright "Will you take a DVD-R?" they will automatically assume you have no idea, take a DVD-R. This will get turned into DDP by them, as they will (often correctly) assume it is quicker for them to PreMaster your disc from a reference copy. You'll pay extra for this as well. They will of course deny it, but your bottom line will go up.
