Starting point: MP4 - H.264 video with AAC audio in one file. H.264 has no alpha channel, so transparency is dropped. Ripped discs may split titles across files; convert each title separately. Encode VOB (MPEG-2 / AC-3) from MP4 at a bitrate near the source, and confirm the audio track before converting.
