XP does not have native DVD recordable media handling so that's not a bug.
As to the softwares listed, those may work but given the above you seem to be trying to use Explorer on blank DVD media which is always going to be trouble.
However if I never use Explorer and run my DVD recording software (either what came with the drive or a retail purchase) I never have an issue. Your issue may be as simple as you trying something that should never work.
MY DVDRW becomes a cd drive when I insert a DVD+ or - disc into it. Under My computer with no disc it says dvd-ram drive, but once that blank dvd goes in, whammo it's a cd drive. Even if I try to explore the disc I get "F:/ is not accessible. Incorrect Function."
I'm running Windows XP pro, 64 bit version. My dvd drive was a Toshiba Writemaster model # SH-s182. Thinking it was that I went and bought a new DVD Drive, a memorex 20x multi format with lightscribe, model #MRX-530L, but I get the same problem.
As far as burning software I've tried MagicISO, Nero essentials, and just exporting my Adobe Premiere files to dvd (which is what I'm trying to burn) to no avail. I've also run CCcleaner in case it was some old reg files and no help.
I've found similar posts but no one seems to really be able to answer the question. Any help is greatly appreciated.
