I'm confused on a few things
What softwares did you use for making this PAL disc ?
I'm not being smart here but to make sure the term is correct.
"ripped" means read . Usually it means read to the hard drive .
At what point in this process ?
Maybe you can post a "Text" from MediaInfo from one of the .VOBs .
Usually the largest is the best to use. This would be your "Source" .vob's.
Also one from a .VOB on the ImgBurn burned(written) disc.
This will tell me at least a couple of things . The resolutions & if everything is still PAL.
