dbminter Posted February 2, 2014 Share Posted February 2, 2014 I had an image created by Macrium Reflect of its recovery environment. I edited it with UltraISO to add some folders. When I loaded the image in ImgBurn to burn, I noticed I could edit the ISO9600 label field to have a : and spaces. I thought ISO9660 was no special characters like colons and no spaces, using underscores instead. I also noticed there are apparently 3 different options for ISO9660. The one selected was DOS. Is the ISO9660 for DVD Video images something else that doesn't allow these characters and is therefore different? My only real experience with ISO9660 label fields is for DVD Video and these Macrium Reflect images. I just never tried changing the ISO9660 field before for these Reflect images.

LIGHTNING UK! Posted February 2, 2014 Share Posted February 2, 2014 The original spec for ISO9660 was really restricted / limited (this is what the '1988' option in ImgBurn's Build mode corresponds to). Since then, things have become a little more relaxed (the '1999' option). Link to comment Share on other sites More sharing options...
dbminter Posted February 2, 2014 Author Share Posted February 2, 2014 So, I'm guessing DVD Video uses the 1988 standard since DVD Video was introduced around 1996, just before the 1999 standard could be introduced. Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted February 2, 2014 Share Posted February 2, 2014 DVD Video shouldn't really use ISO9660 at all and I don't know why they bother putting it on the disc. I'm sure everything would use the UDF file system over that one and they play the data based on pointers / offsets within the IFO rather than looking at file system / file names (beyond the IFO) anyway. You'd have to check the specs to see what they say about ISO9660 restrictions. The folders/files have very specific names (lengths, and all uppercase) so yeah it's probably going for 1988 for maximum compatibility with really dumb, old players.
