SOURCE: samsung yp s3 doesnt work on xp

I have Windows XP and Media Player 10.

I had same problem with Samsung media studio not recognizing MP3 player. Here is how I fixed it. With the MP3 plugged in, I had to go into System/ Hardware/Device Manager and find the S3 driver under "Windows portable Media" and uninstall it. Then unplug and replug the S3 into the usb so that driver gets reinstalled.

Then I decided windows media player and samsung media studio are unnecessary for transferring music files to MP3 player.

Instead I go into Portable Media Devices from the control panel and just treat the MP3 player like a usb device. I copy folders of music and songs into the Music folder on the MP3. For me this is way easier than the Samsung music studio or Windows Media player.

After 2 days of figuring out, I came with the solution today. Most probably your computer is running under windows vista. well emodio doesnt support such to do the transfer. What I did is downloaded a program (free) called "any video converter". All videos have to be converted in WMV extension file, so emodio can recognize and does the conversion to SVI ( the yp-s3 extension). So after you convert the original files into WMV files, take the converted files and add them into emodio. Emodio will convert it into SVI, but the transfer to the MP3 will failed. This is the magic:

close emodio. Leave your MP3 conected. Go to where emodio saves the converted files. When u go to that folder, you will see your files, but you can tell your computer wont be able to play it, as the files icon is just with a white background. Just drag it into the YP-S3 video folder and voila! Disconnect your MP3 from the computer, turn it on and enjoy your videos!!!!!!!!!!

Dude when you connect your mp3 player to your pc then hold the usb lead or cable properly and tightly then it will work..!
