This info has been posted before, but an occasional reminder won't hurt, especially if you're new to the forum:
I received two DVD which had been formatted in DVD-VR mode. Because all of my stand alone DVD players are compatible with this format, I didn't even notice it. But tworecipients replied back with incompatibility issues. So the first lesson as you author sets, is be sure to format the DVDs in video mode and not VR mode.
How do you tell if dvds you receive are in DVD-VR format? Instead of the usual two folders on a disc formatted in video mode (AUDIO_TS and VIDEO_TS), you'll see VIDEO_RM and VIDEO_TS on dvds in DVD-VR format. With either format, DVD Decryptor goes right to the VIDEO_TS folder to extract files.
Next, how to resolve the problem to increase compatibility with all stand alone DVD players? What I tried last night was importing the individual episodes into Ulead Movie Factory, setting up an entirely new menu, and then burning to a new disc in video mode. This then produces a DVD with both AUDIO_TS and VIDEO_TS folders.
If you know of a way to make the conversion more directly, without mucking around with new menus, I'd like to know, but for now Ulead seems to be an adequate answer to the problem.
