I've owned the Panasonic UDP 9000 for perhaps two and a half years or so now. For a while now it's been having a difficult time reading discs. I get a message after a few minutes reading "cannot read disc" or something like this anyways. I eject and try again. Sometimes it will end up successfully reading the disc after I rotate the disc to a new position and place in the tray again. My girlfriend says she thinks it might be dust interfering inside the unit on the lens or something. The same thought crossed my mind. Anybody have any ideas on how to remedy this? It's extremely annoying and I don't want to have to drop over a G on a new player so early on after owning this one.
