Nah this is just loading in the image file. The sequence of numbers (the signature) i look for in the .gi file must have changed - or at least is different for this image. Without that sequence, it's not classed as a supported .gi file and then defaults to opening via normal means - i.e. as if it were an ISO image. As an ISO must at least have 1 sectors worth of data in it, it's failing because it doesn't. (1 sector being 2048 bytes).

Were you just burning the exact same ISO and not the raw VIDEO_TS files? If you were burning the files, recordnow could just pad the filesystem so 23 could have been correct. If it was dealing with the ISO directly, ImgBurn should have also picked up cell 23 as being valid if indeed it was (and you'd have been presented with a nice little selection box). You can't really manipulate the ISO once it's been built, so recordnow max should also have gone for 25 as it was the only valid one. The only way to tell for sure if RecordNow was ok to use cell 23 is to look at the disc it burnt, find the offset for the VTS set (in terms of LBA of VTS_xx_1.VOB - use IsoBuster or something) containing the layerbreak and then the offset of cell 23 within that VTS. This can be found using IfoEdit. From the original IFO files, Cell 23 starts at LBA 1637074 (offset from sector 0 in VTS_xx_1.VOB). 1637074 (mod) 16 = 2 So, if my calculations are correct VTS_xx_1.VOB start LBA (mod) 16 must equal 14. Only then will Cell 23 fall on an LBA where it (mod) 16 = 0. The rule for layerbreaks is in the DVD Video specs - or at least the double layer recording version of them. I don't have them. The info was passed onto me by someone and backed up by what I'd read elsewhere (mainly on the gear mastering site) However, a quick search on google finds the following: http://www.gearsoftware.com/support/docume...mbreakpoint.cfm http://www.mediachance.com/dvdlab/Helppro/layerbreak.htm

You should take a look at what upper/lower filters are installed. You can get a util to do that from this website: http://www.bustrace.com/downloads/free_utilities.htm (It's called 'Filter Driver Load Order v1.0.005') The upper/lower filters are drivers that all I/O passes through in order to actually reach your DVD drive. As such, I guess something between SPTI and DVD Drive is messing things up and VSO doesn't pass through it.

Any chance you could attach the little tiny .gi file you're trying to load? Oh and this is just a simple data disc type image yeah? It cant handle multi session / track images.

Fordman, Quite right, you don't need to do the grab5m thing now. That truncated address calculation could have meant ANY file got changed (rather than the bup). It might not have even been a file at all, it could have been something in the filesystem. I'd love to see an original disc where the layerbreak isn't on a sector divisible by 16! Not that I've ever really been paying that much attention but I have to say this is highly unlikely.

It doesn't keep it, it re-finds it. PgcEdit passes it via a CLI command parameter now. If PgcEdit doesn't physically call up ImgBurn to do the burning (i.e. you load ImgBurn manually), it's ImgBurn's internal IFO parsing code that's finding the layerbreak (as indeed it should do).

If you have anydvd/dvd43/dvd region + css free installed, please ensure they're disabled before you verify anything.
