1st. mosaic cant be read on my windows mediaplayer as a device.

afaik, you cant open a corrupted file even with newer codec.
just try to redownload the file again and if it still cant open, try to reinstall/upgrade your mediaplayer

Hi

Try to download VLC-mediaplayer from:Videolan.org and try with this program. and/or:
i allways use Mediaplayer Classic http://mpc-hc.sourceforge.net/ this works really well for me
and plays ALL Media. also download and install FFDSHOW: http://www.free-codecs.com/download/ffdshow.htm (this is the codec for media files)

Good Luck

if ur device is formated by the mediaplayer then u hv to use the recovery software ......such as Data Recovery from
http://www.recovermyfiles.com/

Try removing or deleting the second account. It may be that only one account can be associated with the mediaplayer.

Let me know if you need further assistance.

Runa Repair in the Philips Device Manager to start over from scratch. Or, manually delete every song using Windows MediaPlayer. Either way.

delete the media player software and reload it as this 1 which you have loaded must not be loaded perfectly.also try to load mediaplayer --8 or 9 instead of 10 ,11 as your operating system must not be supporting this.

Found the solution on another site (http://www.everythingusb.com/forums/showthread.php?threadid=11238). To quote user AFHavemann :

"* Plug in the player so the USB bus can see it.

* Once it’s recognized (i.e., the device screen reads "Charging" and "USB Disconnected"), go to the Control Panel and click "System"

* Choose "Hardware" then "Device Manager" tab.

* Look for the name of your device under “Portable Devices” in the list

* If the name of your player is under “MTP Device” then the correct drivers are probably loaded

* Right-click on the name of your device and click "Properties"

* Click “Update Driver”"

Then follow the prompts from there. The computer searches for the driver software, etc., and reinstalls/resets information related to the device, which fixed things such that the computer will now recognize the device. I'm not sure what causes the problem, but this solution seems to reset whatever's gone wrong.

did u try the sync option on mediaplayer my wifes sandisk likes to use mediaplayer if not make sure u have the drivers for it

You could be getting interference from another program trying to access the player. For example when I plug mine in samsung media, multi media, and windows media all try to connect to it at once. I notice I can't get anything done untill I disconnect the connection or the sycrnization from these programs. I usually let them sync then stop each one, and go about my business.

Refer to the SanDisk site to update your player. Your pc probably isn't the problem.
