This pertains the file via the link on fanedit.info for RS DL NTSC:
When burning, I got the same ImgBurn prompt: "This image has not been mastered correctly for burning onto double layer" as TML. I burned it anyway, but the DVD skips a lot.
When I saw Chewtobacca's advice in this thread, I built + burned an image from the VIDEO_TS folder. That burn went fine and there was no prompt (I chose layer break at chapter 27, because ImgBurn rated it as "Good"), but the DVD still has issues with numerous skips, especially in the beginning of the movie.
The ISO file plays just fine when mounted on my PC, but I'd really like to get it on onto a playable DVD. Any advice?
