I got the same problem. My Dvd plsyer is Pioneer. I found out that some dvd models 'choose' plates. it's lime they have code or something to be able to read before the player 'agrees' to play.

Your DVD player is fu.k.d up.  These things are made so cheap now a days that it is more trouble to try to fix the thing, than going out and buying a new one.  You can try running a disc head cleaning kit through it first to see if that helps.

You need to make sure that you have at least 50MB of free space for the player to load the database. If you have at least that much space then it is likely that the firmware has gotten corruped.

First, connect your player and back up any important media items that are on it.
Next, download and run the firmware installer from the RCA website:

Try unhooking the battery for 5 minutes

Is your BluRay connected via HDMI? and if so, are any other sources connected the same? if not, just for arguments sake, try hooling up the BluRay via component and digital coaxial or optical. Yamaha as well as all other AV receiver MFG have had big issues with HDMI processing. HDMI has been battling with the recording industry over HDCP and copyright issues on recording via HDMI. So, that's why HDMI has been so flaky. It's been thru versions 1.1,1.1a,1.2,1.2a,1.3a, and now 1.3b, which seems to work so far.... Anyway, sorry to stray off topic, however, HDMI has been a blessing and a curse for both professionals and consumers alike and has caused multiple strange issues with all products that use the technology. Hope this helps. Post a comment if you need further help. I've got lots of contacts for crazy issues!

Try another service pack on your windows XP or use Winamp ( Newest version ) To transfer music to your mp3 player.. hope it helps :)

The unit can recognize that a disc has been loaded but can not read the contents. This can be as simple as a dirty lens or more drastic like failing optics. Try cleaning the lens using a cotton swab and alcohol. If that fails to correct the problem and a music CD will play OK, then the optics are failing. DVDs require more laser power to read than a music CD.

The songs might have a virus in it or they might be corrupted. Reformfat the sandisk by going into MY COMPUTER and then finding the devices icon and right click on it and click on FORMAT.
