    Dumb question, but pertinent. I have an ibook with a uj 835 superburner. Now, can I burn regular dvds with this on idvd or toast 7 and expect to play them on any type of dvd machine or am I limited somehow by some problem with these Apple superdrives?

    Thanks -- any comments would be 'preciated.

    DVD-R DL is a dual layer recording - hence the approx 4.7 GB of a normal DVD-R becomes approx 8.5 GB when a dual layer machine is used.

    There are a couple of problems to be aware of, though. First, most normal DVD readers can't read the DL format, so if you create a DVD-R DL, you can only send it to someone else with a compatible reader.

    Second, the cost of the disks is very high per GB compared with normal DVD-R's. I buy my 16x DVD-R's in bulk for about 35 cents each, and I think that the DVD-R DL blanks are about $3-5 each.

    But the biggest drawback for me is speed. My La Cie reader does normal DVD-R at 16x speed, but using the DL option drops it WAY down.

    Anyone have the earlier model UJ835 superdrive in their mini or PB or iBook that they can tell me about any problems they may be having with it? Thanks

    Does anyone know how the uj815 burner in my older Tibook 1ghz burns differently than the UJ 835 or UJ 845 Panasonic for Apple laptop superdrives?

    I'm thinking of dropping the uj 845 burner into an ibook or into the old Tibook.
