The w600i plays mp4 files well. Convert them then stick them in the folder that holds the camcorder video clips. When you have your phone connected to the pc using usb cable, you can go to my computer on windows and your phone will show up as a separate device. You can drag and drop from there.
Mp4 works for me. Never tried 3gp files. What program are you using to convert these files, or are you finding them on the net?
