This reminds me of Flexplay, which was a DVD that had a coating which made the disk unreadable after 48 hours. Technology Connections did a wonderful video about it.
I used to put them in a plastic baggie, push all the air out, then stick it in the freezer. It seemed to halt the process long enough to give it to a friend and allow them watch it after the 48 hour period.
