So... my guess is that this is some kind of option/protocol mismatch problem. I'd love to help debug this as a built in kernel solution to me is MUCH more preferable to a userland/isofs solution. I want to be able to create ext2 file systems, ect. I have experience coding, but none playing with the kernel or the guts of a dvd rw/packets so im not quite sure where to start debugging this. Anyone want to give me a quick heads up?
Some ideas:
* This seems to be a problem with fast blanking, not packet writing, so asking Jörg Schilling or on the CD recording mailing list (there is a link on Jörg's web page) might help. I'll ask/look into it
* Does full blanking work in cdrecord?
* Does cdrwtool work if you start with a blank CD and format it without blanking it from cdrwtool? (I think cdrwtool -m will format without blanking first, but I'm too lazy to check the source code.) Welp, Since i have no way to "blank" a cd in linux (besides the format tool

Actually, I'll do that later tonight.
* Does packet writing work if you start with a CD already formatted for packet writing? See above, I'll try it tonight.
