Just tried it for the first time, and no luck. Inserted and it said invalid media. I followed 94explorer's instructions to no avail, at least the first time. I used Imations, and am now going to try Fugifilms. I just read something about the DVD recorder having to be able to make DVD ROM's, and my Sony will not do that. I guess that's the next thing to look at? Sorry for the ignorance, but this is all new stuff. I haven't even begun to get to the stage about mounting, changing stuff in the PIM, and other things that have been discussed.
