There is no link to JACKET_P and OPENDVD from the VIDEO_TS folder. If you want these 2 folders, then copy them onto the final dvd compilation at the same level as VIDEO_TS folder, just like the source DVD, and burn them with Imgburn.
Only some DVD players are able to display background image in the JACKET_P folder when the DVD is stopped or ejected.
What is in OPENDVD folder? Probably some data files. Are there files in the dvd root directory? It could reference this folder to function probably.
Both JACKET_P and OPENDVD are not required for the DVD to work. The only required folders are VIDEO_TS and AUDIO_TS.
Mod: could you move this thread to the DvdReMake forum. Thanks.
