i made 2 dvd copies yesterday of a one-hour movie i edited with vegas 5.0, using DVDA 2.
first, i prepared the dvd.
then, i burned copy number 1 which took about an hour.
then, i burned copy number 2, which to my surprise, took only about 20 minutes! later, i checked both copies and they were ok. is this normal? that burning a second copy of a dvd takes about half the time it took to burn the first copy?

Hi,

Yes it's normal since the prepare process was already done when you burned the second disc.

yeah, i know. but i'm not talking about the PREPARE DVD process. i'm refering to the BURN DVD process alone. does this process also have some kind of preparation process, or does it make temp files, which don't have to be re-done when making a second copy?

When you say ou "prepared" the DVD, exactly what do you mean? Did you let it create all the VOB files, directories, rendering, etc? Or do you mean you just created all the menus, links, etc?

I don't think it needs anything like temp files. I have actually taken the prepared directory from DVD-A and burned it with Roxio because DVD-A was sometimes not burning DVDs. Can't explain it but I would try to burn the DVD and it would finish halfway through "Burning Lead-in" and say everything completed correctly, when of course it had not. But that doesn't sound like your problem because it definitely didn't take 20mins. But I know there are no temp files needed because you can burn the DVD with any program just using the prepared files once it's prepared.

I would check the DVDs carefully... make sure they both play, that the files are the right sizes, etc.

A couple of things are possible, though:

1. For some reason, your burner decided to run in a different burn speed the second time around. For example, the first time you used a 2.4x media and the second time you used a 4x media. Or the first media was an RW and the second one was an R?

2. If you were using the computer while it was burning, you could have slowed the process down. I can do this because on my system it never coasters CDs or DVDs, but it will slow down the burn speed sometimes.

1 hour for a dvd burn, even By dvda standards that is very slow.

Why it burned 2nd cd faster is a mystery, you are correct in thinking the Vob/ifo files should have been "Prepared" in the "Prepare" stage.
from there it should be a simple burn.

Personally I have started to load the video/audio folders into nero for the burn stage because Dvda ( unlike cda) is a little tempremental on the burn, terrible with " Tme estimates" etc
