DVD Studio Pro — some DVDs working in normal DVD player, others not
Hi all-
I just burned 40 DVDs of a short film in DVD Studio Pro. They all worked perfectly when played on my Mac, but when I try and play them in normal DVD players, some work and some don’t. The ones that do work in both players I’ve tried, and the ones that don’t work in neither.
Since they are all exact copies of each other, I’m trying to figure out what the problem is. As far as I can tell there are three possible reasons for these differences:
1) Different brands of DVD. I bought 2 brands of the same type of DVD. Maybe one brand works better than the other?
2) Copies made by a DVD copier work worse than copies burned by DVD Studio Pro. I burned about 3 or 4 copies using DVD Studio Pro. The rest of the disks were burned using a DVD copying machine with 7 trays. All of the discs were verified by the copying machine, and then I played them on the computer, and they all worked fine.
3) Certain trays on the copy machine didn’t work as well as others.
None of these really make sense as an explanation to me, but since these are the only three variables, it has to be one (or a combination). I need to submit this short to festivals, so it has to be sure to play both on computers and on DVD players. Any advice on what I should change when I make the next batch to guarantee that they work would be really appreciated. Also any insight into what went wrong would be helpful as well.
Thank you all so much!
