I have a strange problem I've encountered with a couple of dts conversions of recordings I have. I had not played some of these in a few years, but do know that they played fine at one time. When I attempted to play the recordings recently I've encoutered a few they will no longer play. It's not accurate to say the files have vanished. When you open the folder for the disc, there are still files there. They just will not playback. Has anyone else encountered burns of dts conversions that once played and then quit playing for some reason? Concerns me a bit because I have a lot of conversions of my collection and I'd hate to think that they all ultimately are going to be unplayable. Any thoughts or advice on the problem would be appreciated.
