Jiri Zita Posted April 7, 2008 Posted April 7, 2008 Hi, I think there is a problem with MDS file creation in ImgBurn (using 2.4.1.0 but probably in every older too). It contains improper information for DVD9 OTP discs so our premastering software crashes when it tries to read the mounted MDS image (through Daemon Tools 4.12.2) of OTP DVD9 disc. Please see attachments and you will find the differencies regarding the "Last Physical Sector of Data Area". MDS+ISO files were created by Read function in ImgBurn from properly prepared OTP DVD9. Probably there is a wrong calculation somewhere during the creating of MDS files. Of course we can mount supplied ISO images but then we have to manually change layer breaks in our DDP premastering software. MDS+ISO could be better solution. I hope this post will help you improve your great piece of software. We like using it :-) Best regards, Jiri Zita Premastering department GZ Digital Media Lodenice Czech Republic
LIGHTNING UK! Posted April 7, 2008 Posted April 7, 2008 I only care about the layer break position so I haven't made any effort to make anything else the same. I'd be interested to know how 'Last Physical Sector of Data Area' is actually calculated if you know?
Jiri Zita Posted April 7, 2008 Author Posted April 7, 2008 (edited) I only care about the layer break position so I haven't made any effort to make anything else the same. Yes, I understand, but then the MDS file is usable only in your software. If ImgBurn shows that information from OTP DVD9 disc then it also should be correctly saved in MDS. So we can emulate the disc properly in Daemon Tools.

lfcrule1972 Posted April 7, 2008 Posted April 7, 2008 Mmm I think I got lost when I forgot to carry the 1 at the start !
LIGHTNING UK! Posted April 7, 2008 Posted April 7, 2008 Ok, that's easily done I will change it to use the real data when read in Read mode but I can use your calculation when I create my own from Build mode. I'd never have guessed at the XOR'ing! Many thanks

I'd never have guessed at the XOR'ing! Many thanks Hello, If you want I can do some betatesting with several MDS files and DL DVDs we have here. I can also compare the results with our DDP creating software if it shows the correct numbers for layers. The only thing I need for that is the new version with better MDS support you mentioned. You can find my email in my profile. Thanks for your support to ImgBurn. Jiri Zita.

LIGHTNING UK! Posted June 6, 2008 Posted June 6, 2008 The MMC specs say that for OTP media, the physical format info for each layer is just a copy of the 1st, so I'm not seeing any reason for the 0xDDFBD0 value anywhere. On PTP media (the ones i've tried anyway), the 'First Physical Sector of Data Area' is still always 0x30000 for both of the layer descriptors. There is no way to store relative paths within the MDS in ImgBurn, it wasn't designed to support it. It's either an absolute path or just the file name - mainly because I saw no reason for the type of paths you're saying you need. I'll see about implementing it for the next release.

Hi, If the MMC specs say it then it is true for sure. They are the authority :-) I've only tried several combinations to make it work (reading of mounted MDS) so that our app wouldn't crashed and I've found one which works. Probably 0x30000 will work too, I will test it and correct the MDS. It had already worked before with that wrong number. For mastering we need both layers in DDP format to be in separate folders. The best thing to test final DDP master before production is to mount the DDPs. We use CUE sheets for most other formats but for DVD9 we need MDS files with relative paths to subfolders. The MDS file will be saved into parent folder of both layers folders and then we have a possibility to mount the whole DVD9 title either on the local hardisc, either on the network. We will implement this feature in our own app so don't bother yourself with it if you have more important things to do. I thought it could be interesting also for someone else. Jiri Zita.

LIGHTNING UK! Posted June 6, 2008 Posted June 6, 2008 Would you like me to send you a private beta so you can test it with your other software?
Jiri Zita Posted June 6, 2008 Author Posted June 6, 2008 ..........I've done the relative folder thing now - providing the images are in folders that are subfolders of the one where the mds is. Great You are soooo fast that I am not able to think out and write new suggestions and requests for you :-) Thanks. But wait! .... Yeah! I've got one. I will write it in Suggestions forum soon.
