I'm running Win XP Pro, all updates, using Optorite DD0203, Firmware 2.16, with Sony & Maxell +RW media and I get the 'Module sfmmcx.cpp' errors AFTER doing the 1.0c update!
Somebody please post a fix! I know there are workarounds, but this program should do it all!
I'm not quite sure what "this program should do it all" has to do with the rest of your post, but it seems to me that you might look for a driver problem or OS problem first. Since this problem doesn't occure with most people it would seem to indicate that it is a problem with your system rather than with the way DVDA is programed. But I could be wrong I suppose.
