I thought at first this may have been an isolated incident with my drgonheat dvd which i have tired in no less than 4 different players just to be sure it wasnt an issue with incompatability. I was all set to watch daylight the other day and the exact same thing..the message comes up saying " try a different disc. There are no fingerprints or scratches,( i have tried cleaning them anyway from center to edge of course, with an appropriate cloth-- no luck) they are always put back in the case after watching them, and they are not near any source that would possibly cause damage. ( like extreme heat).. the problem is, i have owned both for at least a year and a half, so exchanging them is out of the question. I e-mailed universal last night, but as of yet have not gotten a reply about an exchange (IF they would do that).. anybody else had this happen where the movies, for NO reason at all just won't play anymore. This really stinks. Makes me wonder how many other dvds are going to do this.
