Burning CD's in Vegas

I'm running into a situation when I burn CD's in Vegas. It happens every time I burn, but I'll provide two examples of the problem for illustration.

The first CD contained one track at 51:16. I'm burning at 8x. Vegas tells me the disc will take approximately 6:56 to burn. First it starts the lead in, which it tells me will take about 12 seconds. After the 12 seconds elapse and the duration bar fills up to 100%, it takes an additional 35 seconds before it gets to the actual track writing. The track writing time is estimated at about 4:10, but it takes about 12:30, over 8 minutes of which happens after the duration bar fills up to 100%. The lead-out does the same thing as the lead-in.

The next CD contained 52:05 on one track. It's lead-in said 13 seconds but took 52. It's track writing showed 4:18 and actually took 12:43. The lead-out also took much longer than estimated.

All the CD's I burn play normally.

Any thoughts?

I don't know if the code is related, but when i burn Audio CDs in SIREN something similar happens. Sometimes the progress bar stops completely for a minute or more and the drive actually spins down to a stop (*shudder*), then resumes again. The discs all play fine though.

That's funny, I have the opposite experience with Vegas 4 (3 also if I remember correctly). The progress bar only reaches about 60 % then the burn is complete! Everything's fine on the CD, no biggie, just scared me the first time I saw it.

I wonder if it has to do with the burner. I'm using a Sony DRU-510A.

I think the majority of it can be sumed up to that the time is nothing more than an estimation. There's a lot of things going on in the background when you burn a CD. A lot of Read/Write and Retries and error correction going on. And of course that will all very from burner to burner depending how it handles that. That's also why burners have buffers, so it can buffer that information and keep up a constant stream of data to the burner to stop you from making coasters. You see the same thing in just copying large files between hard drives in Windows. They give you an estimation of how long it will take to copy the file, but have you every really sat down and timed the actual time to the estimated time?

Could be drive-related.

In CDA5, when I burn to a LiteOn, the progress meter only updates each timen I move the mouse ! Replaced it with a Plextor and everything works as you would expect. Just to be sure, I went back to the LiteOn (breifly !) and the problem came back.

Or it could be something in SoSoFo's common(?) CD writing modules that just clashes with the LiteOn ....
