I purchased a 4gb MP4/Mp3 player on e-bay. There is no brand name but is was made and delivered from China. The player came with a broken/cracked CD to install operating program on my PC. The seller would not send me a new CD but directed me to S1mp3.org website to get a download. Because there are numerous dowloads available I asked which one to use. The seller would not reply. The Problem: in the Movie mode, I do not know how to download music vedios to the player. Can anyone help.
