Basic DVD questions
Just a few basic questions - am I correct in believing that the final video files on all standard DVDs are VOB files, and that they are always authored from MPEG-2 files ? In other words, files such as H.264 and AVC files would have to be converted to MPEG-2 before going to VOB on a DVD ? Also, is MPEG-2 by definition an interlaced format or can it be encoded as full frames ?

VOB files use MPEG-2 video compression with a variety of options for audio (PCM, MPEG, DD). Anything that's not MPEG-2 and of a file size that will fit on DVD disk (DVD-5, DVD-9) must be transcoded before burning.
Compression formats are generally independent of whether footage is interlaced or progressive. You can transcode interlaced to progressive, or interlaced to interlaced. You might be able to transcode progressive to interlaced but I cannot imagine why. I've never heard of anyone trying it.
