MP4 player problem accessing menus.

[melodymaker]

I got an unbranded (samsung electronics) MP4 player from Ebay from a seller with a good reputation. Its great but I can't seem to scroll down all the different folders (artists/albums) in the menu. Everytime I get to the "local folder" where the artist's folders are, I can't scroll through and make a selection because 1) I can't scroll down 2) The screen very quicly goes off and then the last song that was playing is displayed. This is very frustrating as the instruction manual is very bad English and doesn't explain this. I have managed to do it before but mainly it doesn't work. I have bought the same player from a different seller and the same happens with that one so it can't be a fault.

I may be doing something wrong. I convert the albums via Windows Media Player's "rip it " function. Then I simply drag and drop the folders (albums) into the drive.

Can anyone help?
