I have a quick question. I noticed that DVD Architect creates two file folders; a VIDEO_TS and an AUDIO_TS. Does that mean I can delete the original MP2 and still burn a DVD from the specified VIDEO_TS and AUDIO_TS folders?
Yes - The folder with the VIDEO_TS and AUDIO_TS in it is the result of the "prepare" operation. Once that's done, then burning only requires that folder - unless you change something and need to "prepare" again.
