I just got myself an mp4 player off eBay and when I first turned it on all that it showed was a time dial. I tried charging it but that didn't work and I tried to let the battier die but nothing happened. Not sure what else I can do for it, any ideas?

What make and model?

I'm not sure how advanced a media player you're looking for but this may help you. It explains how to choose an mp4 player that's best for you and lists several available. Many are free. http://www.real.com/resources/mp4-video-player
