what can i do if stuck with recovery mode ? i had done reboot , format , clean up and reload firmware but it doesnt worked at all . does it cannot be fix anymore ?

because that format is not supported by the media player in which you are playing the movie . Try with the VLC player

windows media does not support all extensions. Below are the examples. if you have the right format and still you are not able to play then best option is to upgrade or reinstall media player. Windows Media Player 6.0 loadTOCNode(2, 'moreinformation');

Have you checked this out with another PC please try this out. In the player gets detected then the fault could be failure or virus in your system. If so use a good antivirus to scan and delete any malwares. you can also restore your PC to an earlier set point. open control panel and use the restore settings if you had set this up earlier. If the same fault is seen on other PC then you might have a program fault in your ipod. Try to repeat the reset / formatting once again hope I could help . Good day

These are the most common methods for recovering Sandisk's Sansa Mp3 Players. I have been almost universally successful in recovering Sansa players using one or a combination of these methods. These methods do not work if you are having synchronization or music format issues - they are for recovering a player that will not power up, freezes, flashes, is not recognized by the computer, and a host of other issues.

Reset the Sansa Player first. On most models, restart is done by holding the power button in for 15 seconds or longer. Check your specific manual to be sure. The manuals are available from the Sansa website if they have been misplaced.
Download the Sansa Recovery Tool from the Sansa website.
Format - Erases Everything: Connect your Sansa player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "Sansa 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.
Firmware Upgrade- Erases Everything: Get the latest firmware upgrade from Sansa - it updates the firmware and erases every song in the player all at once. Note: this method doesn't work if already have the latest firmware. Go to this website and click "Firmware Updater" to find out: http://www.sandisk.com/DriverDownload/driverList.asp
If these fail, then:
Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.
If you get the problem where MTP Device keeps popping up continuously, uninstall the “MTP Device” by going to Start à Control Panel àSystem à Hardware à Device Manager (you computer may vary slightly, depending on Windows Version).
You may have to restart your computer after each of these methods to get them to work properly. Disconnect your Sansa player BEFORE shutting down your computer.

The below was copyed from an earlier post of mine. Over a period of time your info can get corrupt from transering music back and forth. To format plug it in to usb. Go to my computer It shows up as a removably disc, usually drive f: Right click on drive f: (or the approriate drive) and click format. Let me know what happens, you will have reload the player, also try bypassing the software you are using to tranfer, by opening up drive f: and clicking and dragging your music into it , or you can copy and paste it into drive f: L8R
