Worley,
I cannot say for sure.......I would have to investigate the computer. However, if anyone would have rights to burn I believe I would. I had the computer built (same guy that has built 3 such computers for Vegas/DVD-A). I spoke with him yesterday about the problem. He suggested I try burning a DVD and CD with Nero outside of Vegas/DVD-A to test the burner. That test burn worked fine. Although these are school computers they are used exclusively for video editing.

I have had someone suggest an uninstall/reinstall of DVD-A. Does that seem like a logical fix to you?

There might be a serious burning issue here. I normally create the VIDEO_TS folders, and burn with other software. But the other day I was testing something, and wanted to burn with DVDA4b. I write to DVD+RW discs in an external burner connected by firewire. DVDA4b burned the disc and all, but when I go to play it, the original project from my previous burn to that RW disc was still there (i.e. as if the new project was never written to disc). I tried 3 different RW discs, and the same thing -- in all cases the original material remains on the disc after DVDA tells me the burning is complete. It looks like it's burning because the lights and all are flashing on the burner unit during the burn, but nothing is getting written???

Exactly! this is my problem as well. I am using DVD-A 3.0. The program goes through the entire burn process (I use DVD-R), I can see burned data lines on the DVD but when I try to read it.........nothing there! The burner worked fine on a test with Nero. I am having similar issues with a second computer at school running DVD-A 3.0 and other error messages as well. Sometimes it works and sometimes it does not. However......on my home computer with DVD-A 3.0, never a problem burning. (knock wood).. I am perplexed.

George if it helps at all, or gives a hint or anything on Dxing... Going from memory -- over at the imgburn site read the process of how the format stage gets done using +RW discs. If I'm remembering correctly I think there was something about the feedback from the drive. At any rate, wanted to mention it in case it interested you.

I have had other software destroy +RW CD & DVD discs -- a quick erase/format was supposed to happen, & then everything appeared to be burning normally, but wasn't -- seemed to me as if the erase never really happened, or happened incorrectly, so the drive didn't execute or receive the correct command, proceeded in *test* mode.

While very hesitant to offer too many more RW discs for sacrifice (I'm a Cheap $#!@*), I did find it made a difference using fresh (never written) RWs. Attempting to resurrect the dead RWs, did find both imgburn & Nero Speed offer a full format that is in fact a full format vs. the shorter deal in Nero itself (even when full is selected). Performing the full format saved some, not others, but I noted that the ones that failed burning originally seemed to have the basic disc info (the part that IDs the disc and doesn't change) altered or partially overwritten.

Now that might give a hint or be totally useless -- I apologize if the latter. Don't know if you're motivated to go any further or not for that matter. If you are Good Luck.

Thanks MPM for the reply/info. I usually use IMGBURN for burning (or DVDLab Pro/ProEx burning that is now using CopytoDVD's burning engine).

The reason I wanted to use DVDA for the burn this time was to test how well it burned from a prepared folder that also contained an "Extras Folder" -- but I can't seem to burn properly to the specific external burner to the type of +RW discs I have been using for tests (ruined 2 discs so far). I might be able to recover them by reformatting them in my standalone dvd recorder (I haven't tried it yet because it's currently set to record something for my kids).

Not a big deal for me since I use the other burning software. I'll probably just submit a technical support issue for the problem just to make tech-support aware of the problem I had...

George, I don't have an external burner to try but when I burned a DVD+RW with DVDA4b the burn completed successfully and the DVD played fine. The burner is a Plextor 716A 1.10.
