I used a 4-camera set-up to continuously record a live action performance that runs for about 2 hours (plus 3 non-sync audio feeds, plus a load of B-roll stuff, captions, non-diegetic music etc ..).
When working with the video edit software it became very quickly obvious that stuffing all this into one file was barking mad and that the right answer for ease of manipulation was to chop the thing into chapters. No worries about actually doing that.
The advice I'm looking for is about putting all these chapters (say 20 or so) together on a DVD.
IOW I have (let's say) 20 .mp4 files that flow seamlessly in sequence and I'm looking for the best piece of software to stick these files logically together on a DVD to create a 2 hour film.
