JWG-- the movies will need to be Spruced up before Primo can burn them. Seems I read a post somewhere that SpruceUp is hard to get ahold of right now. You may be better off using something like Ulead Movie Factory to import the mpeg, create the menus, and burn the DVD in one shot. I rip my DVD's with smartripper first. If the whole disc can be backed up and fit on one DVD-R, then I do a straight copy in Primo, or back it up without Macro and subs to shrink it if it's close, then use Primo to burn the files back to the DVD--this will require you to disable the checks for valid name format, just make sure its in the proper structure (VIDEO_TS, etc). If it's over the limit of one DVD-R, I convert it to DIVX, then port that through Magix DVD to CD/DVD and it works out just right.
If it ain't broke don't try to fix it! But, hell if you can tweak that bastard just a little bit more....hehehe.
