A few years ago (2015) I took all my old movies and tapes and sent them to Southtree to put on disc. When I received back I can't remember if I checked even one-but I am pretty sure I did. Anyhow I packed them -in two different places. One was with all my other transfers which I had done myself and they still work fine. I pulled them out recently and now I can't get even get one to play on my DVD player or on my computer. They all say this file is corrupted or unsupported.
