#1 Burning Software

Hi,

I have a new question

1) I use GetTrackInformation() of Invisible track in order to retrieve the available free space on a disc. The issue I have is that I will then create a file that matches the size of that free space, and then put it under some subfolder and burn that to the disc, wouldn't I be overburning ? After all, creating a folder would also take up some space on disc, and closing the disc would also require some space right (my assumption, correct me if I'm wrong) ?

So, my question is, how do I find out how much actual space I can use to store my file after taking into account the folders that needs to be created, closing disc overhead, etc ?

2) Also, after running several tests, it appears Starburn will automatically close a disc if there isn't enough free space for more sessions. This appear to be consistent for all media I tested on: CD-RW, DVD-R, DVD-RW, DVD+RW. Can you confirm that this is consistent for all media, including those that I have not tested on ? It would have been good if information like this is properly documented, then I would not have to waste so much time in testing.

Thanks in advance for your help.

Regards,
Chris

1) Yes, it would be overburning. For CD-R/CD-RW media it's required to write down something like 15 megabytes for lead-out, for DVD-R media first border-out is about 150 megabytes, next border-outs are around 30 megabytes. DVD+R is the same, formatted DVD-RW, +RW and -RAM show true capacity.

2) Unfortunately it's not we but drive

Hi Anton,

Thanks for your quick response as usual

Following up from question 2, is this behaviour of the drive to automatically close full discs standard on all drives ? How full does the media have to be before it would trigger the drive to automatically close the disc ?

Also, why is the drive able to *really* close DVD+/-RW/-R media, but I can't use Starburn to it ?

The reason why I am asking so many questions on all these things is because my app needs to be able to automatically close a disc if it cannot fit another session ... but this is hard to do using Starburn

Chris

Chris,

no, it's not standart. It's up to the drive what to do. F.e. TEACs (original CD-RW burners, not current PIONEER rebranded stuff) support overburn in TAO mode so they would not close session, LGs - would.

On your place I would keep track on the amount of disc space left. If it's just a bit more then lead-in + lead-out for next session (say 25 MB for CD-R/CD-RW media) - I would disable multisession during current burn.

Hi Anton,

Unfortunately, the problem here is that I can't disable multisession in current burn for certain DVD media formats like DVD-R. We discussed this problem in a different thread previously ...

Chris

Chris,

I'll fix this stuff for DVD-R and DVD+R (honest!), however I can do nothing with formatted DVD-RW, DVD+RW and -RAM...

Hi Anton,

Just wanna confirm the overheads for DVD-R. You said it's 150MB for first session and 30MB for subsequent sessions, but my testing shows first session overhead to be about 60MB and subsequent sessions at about 20MB ? Also, for DVD+R, I found the overhead to be about 5MB for all sessions ?

Can you give me a safe figure to use for the above types to use for estimating when to close the session ?

Thanks for all your help

Regards,
Chris

Chris,

I'll burn some of the discs today and would let you know the numbers.

P.S. Larger ones are safer

Hi Anton,

Thanks for your help. Actually, maybe you should create a table with all these figure and put it in Starburn help file. I'm sure there'll be other people asking the same questions

BTW, when's the next release of Starburn coming out ? The one that's will fix the issues I highlighted in the other threads ?

Thanks again,
Chris

1) Good idea. Please let me know - which ones exactly and I'll do this for sure

2) Please see other threads. If nothing would go deadly wrong we're expectin to release major update this week.

Hi Anton,

If possible, it would be good if we can have a reference table for overhead sizes for all the different types of media. But if I had to choose, I would like to know for DVD+R & DVD-R first

Great, looking forward to the release.

Thanks,
Chris

OK

BTW, I think you're waiting for extended TOC API call and for code to override last session on DVD-RW if multisession was previously used? Correct?

To be specific, I'm waiting on:

and

Thanks,

Chris,

OK, so you'll have preview version soon (before we'll create official release). Private DLL you'll have to verify

Great, looking forward to it
