Ok, that didnt help with my questions on what/how to do my project but thanks for taking the time to write something which did raise my hopes that it can be done. From what you said, it sounds like i DONT need to convert the .vob files to another extension before putting on a BD (then view on a PS3/XBOX)???? My files are 720X480. Like i mentioned, ive tried Adobe Elements but it wouldnt export SD to a BD. I tried one of Cyberlinks products but it almost doubled each file size when i imported the .vob videos (example, a single 1GB file became 1.7GB when i imported it). So i wasnt sure what was happening there. I'd love to try a Roxio or any other program if it'll do what im trying to accomplish. Also, im not sure what the last response meant by "multi-part .vob files should be concatenated first".
