Clarification noted.DVDs do not support TAOI cannot see that you have problems with writing CDs in TAO. If you did have problems, I am sure you did send a report....I did try using packet mode with cdrecord. Even though PACKET is listed as supported by the drive, and -packet is a documented option, it doesn't seem to work. I don't know if the -dvd-compat mode streams, there was a discussion of what it did, but I don't remember the details. Compatibility may only be an issue with multimedia destined for DVD players, I certainly don't do that, but I make a LOT of backups.There is no -dvd-compat option.
growisofs only supports packet mode. This is less compatible than the streaming mode used by cdrecord.There most definitely is a -dvd-compat mode, I just don't know without studying the code how it works.
The required space to save the image or time to make the run twice are essentially linear. This increases the space and/or time required to back up.Now I have to go try mounting an individual session to see how good that fake it.The man page mentions using -isosize, but it seems that only works for aYou _need_ to run mkisofs twice in case you do not create an intermediate file.Correct: the first run is with -isosize, the secone one without.fully created image. That's a minor problem for 4.7GB, a larger one for 8.5GB, and when Blu-Ray comes down a bit in media price 50GB will be unavailable n most systems being backed up.??? I see no difference regardless of the FS size.
