Cd/dvd loads up but wont's play anything as soon as cd loads real player or media player freeze up and i cant get the cd out until i reboot my laptop any idea why and how to fix?

Try another Media Player, it may be the File Format. Try this freeware Media Player, VLC, 32 or 64bit?, found here along with Real Player Media Player: http://www.filehippo.com/download_vlc_32/ You can find many freeware/shareware programs here: http://www.filehippo.com/

Try to upgrade the driver for the DVD player. This is done in the Device Manager.
Upgrade or reinstall the software used to play the DVD.
One of the best players for DVD and all sorts of other media is the VLC player - a free download.

Sounds like laser pick-up is defective or needs a real good cleaning

Probably a codec problem on the notebook. rather than a drive problem. Try a 3rd party media player such as Real Player or Quicktime

Does you DVD player read DVD+RW? If you do and still doesn't work, make sure you have an mpeg-2 decoder loaded up in your computer.

install DVD PLAYER from your NERO SOFTWARE CD

I had the same problem, After googling for a few minutes I found the reset procedure for this player.

1. Turn it on.
2. Eject any disk you have in there and close the tray.
3. Hold down the "STOP" button on the player (not remote) until the green light flashes red and the system reboots.
4. Insert disk and enjoy.

This worked for me... mileage may vary.

i dont know what the problem might be but u should try calling sandisk they should know what to do. hope it helps

those kinda players wont play DVD rom disks and certain ones that are made up. DVD-RAM or ROM wont work. Try blowing inside the player for any dust. if it still doesnt work its the maufacters problem. The player will play CD-G audio only, not graphics The ability to play back DVD-R, DVD-RW, DVD+R, DVD+RW, CD-R, CD-RW, and CD-Jpeg discs may depend on recording conditions.
