[Andrew Chap] “I think the videos are in widescreen”
This does not affect the size – it will still be 720×480. However, if you look at wide screen in a 4×3 screen everything will be squeezed horizontally.
I assume that you also have Vegas? Importing the mov file into that should let you examine the properties of the file to determine the aspect ratio, file codec, etc.
[Andrew Chap] “I don’t think you can put HD videos on a regular DVD?”
That is correct. The HD has to be down-converted to SD.Dave Friend

[Andrew Chap] “But the 720×480 still seems small to me, considering the fact that my home computer monitor is 1024×768 which by modern standards isn’t that great.”
Is sucks but standard def is 720×480. Remember that DVD was designed to show standard definition video – on TV sets not computer displays, not HDTV displays. Painful but that’s the reality.

Tom,
Most of the CPU-Geek sites I’ve found show performance test scores that indicate it makes very little difference. Multi-core performs better with some tests while dual CPUs perform better at others.
From a value perspective the i7 multicore seems to be the best bet.

Jason,
I would not go with uncompressed PCM (aiff) if the title is going to be duplicated (as opposed to replicated.) Even if you have the headroom for PCM you’re going to end up with discs that stutter and skip with duped discs. Stick with the Dolby and use the setting you proposed to keep overall bandwidth manageable.
This isn’t as relevant if the title is replicated. The much crisper lands and fall of a manufactured disc are easier to read and so can keep up with the bandwidth required. (usually)

Brad,
I have found that the usual culprit for this behavior is a corrupt clip (or two, or three). The only way to diagnose this I have found is to close the project, rename a clip file (I usually just put an underscore in front of the name.) Alternately you can move the file to some other folder. Then reopen the project. When PP asks about the missing file tell it to skip finding it. Keep doing this until the project becomes stable.
You might find the offender this way but it can be time consuming.
I have had previously good clips go bad when the system hangs for one reason or the other.
Good luck.

Dave,
If…
- You’re sure that the authoring hasn’t changed since you burned a proof disc and,
- That your DDP image is the same as that proof and,
- You use good media and,
- Burn the disc at no more then 4x and,
- Use the verify feature of your burning software
Then your as diligent as can be.
There is one thing to bear in mind about asking for the short replication run proof. Each time the stamper gets handled it runs the risk of being damaged. Also, there is quite a bit of fine tuning that happens to get the press “up to speed” and the setup on the actual run may not be identical to the “test” run.
Personally I think it better to take the actual run as proof.

Dave,
[Dave Fromme] “For Copy generation (CGMS), I change to One [so the Master can produce copies but the copies can’t be copied]”
Set this to none. The setting applies to the replicated product not the DDP image disc (master) you’re submitting.
[Dave Fromme] “Mastering Output format, DDP2.10”
This isn’t real important but DDP2.0 is more often used and preferred by some replicators.
[Dave Fromme] “My question is what do I actually send the DVD replicating company?”
You need only send the files in the Layer0 folder. You can include the Layer0 folder but it isn’t necessary. You don’t need to include T5TEXT.DAT but it won’t be a problem if it’s there.
It is wise to label the disc as containing DDP files and maybe refer to the disc as “Replication Files” or “DVD Replication Image” instead of a “DVD Master.” If the operator is asleep at the wheel you could end up with a lot of copies of the DDP files instead of a VIDEO_TS file set. It happens. Make sure your account rep knows you’re sending DDP files too – for the same reason.

[Peter Greenstone] “Studios over there are always demanding that demo reels be in PAL so I just assumed it really had to be.”
What Noah said is absolutely true. However, if the video is in the PAL format it will look better than if it’s NTSC. The on-the-fly standard conversion isn’t as good as having the real thing.
In other words, it will play – but won’t be as pretty.

[Khashyar Darvich] “So, they are playing solidly on stand-alone DVD players, but only on about half of the computers that we tried.”
All the same O/S make and release version? Maybe you found a bug in that version of that O/S.
Stand-alone players tend to be a bit more tolerant as they have built-in error correction. Drives in computers are only emulating a stand-alone and rely on software for much of what is “in the chips” of set-top players.
As the data can be figured out by one type of player and not another would seem to indicate a physical problem with the disc IMO. If it were strictly a “bad input” issue (i.e. corrupt DLT, out-of-spec build, bad authoring) then wouldn’t all players behave the same?
It’s also important to bear in mind that the replicator will have to mount the stamper (The stamper is made from the “glass master”) in the press again. So if the problem is a physical one due to the molding process it might not manifest again on the next replication run. Then again, it might get worse.
The replicator should be able to tell you if the data on the disc is exactly the same data that was used by the mastering laser. Perhaps they don’t do that on “check” runs? They should on a “real” run.
You have no reason to believe that it is an authoring issue. Frankly, I believe the replicator needs to either make another run or pony-up for third party verification.
If the disc passes a physical QC review I would offer to provide the DDP data on DVD-R. As I explained earlier, this is done by using the PlantDirect feature of Scenarist. The DDP file-set for each layer (as created by Scenarist, there are four files in the set) are burned to individual DVD-R discs. If your replicator can’t handle that then go elsewhere for the work.
Really it comes down to the fact that the replication check discs are not satisfactory. My offer to run the check disc through our QC suite (at no charge) stands.

[Khashyar Darvich] “I am wondering that since the DLTs did pass, and a glass master was able to be successfully created, could there still be correuption on the DLTs?”
Yes, it is possible. Not likely, but possible.
I talked with our mastering guy and he offered to run your check disc through our checking system to see if anything jumps out as wrong. I will send you an email via the contact us link on your website to give you my contact info.
