If you could go with DVDAfterEdit Mastering Edition, it would output the best UDF bride DVD Image to hard drive - and give you the proper extension. Though, I wasn't too happy with it's UDF bridge structure it created, as Eclipse's UDF verifier returned a bunch of errors on the DVD-R output I burned from Discribe (hard to pindown playback errors are sometimes cured by reformatting the Image with a known good formatter).

I also tried Discribe with a 'dangling' VIDEO_TS and AUDIO_TS folders, and it will format a new UDF Image while burning to disc. Or, maybe it's just Discribe - though I loaded up a re extensioned from img to DMG image in it here, just fine. I guess that DMG was formatted without UDF info, and just the ISO files? (Colin: I should have said in my first reply that 'if the re-extensioned Image mountsĪND if Apple DVD Player starts up automatically to play it, then you're good'! Thanks). img, and be the basis for the burn for all client approvals as well as any proof discs that might be sent to the '.labs'. Now, the argument could be made that since this DVD is so old, it might be a good idea to check it's UDF file structure for compliance (who knows what early version authoring system generated it?), and if there were errors found, then it would be good to mount the Image and copy off the VIDEO_TS folder and any other data, to have another modern formatter regenerate a new Image with fresh ISO/UDF bridge information which btw, is what should be done if the duplicator has trouble with Jeremy's re-extensioned Image.įor sure, changing Image extensions is a constant way of life for the seasoned DVD pro For example - the 'final' MAIN.DAT or IMAGE.DAT file in the DDP file set, restored from DLT or hard drive formatting, should have their extensions changed to. So, the Image will have the prerequisite UDF file structure and a duplicate ISO file structure (hidden to Finder) tacked on to the front of the VIDEO_TS folder and any ROM data, which is supposed to perfectly describe were all the folders and assets are located, by sector number, so the various OS's the DVD might play in can find all the data during navigation. Since this is an 'old DVD Image', it will have to conform to a modicum of spec compliance, i.e., not contain any of that 'worrisome' stuff. Based on the provided information, I think Jeremy will be OK.
