I have just bought 1 of these. I have added music no problem, however videos just do not work. I have tried mp4, avi and mpeg but none of them play, whenever i try transfering the movies over it says they need to be converted but it doesnt say what. I have checked through the manual and it says it plays all of the files i listed so im a little confused. I have checked their forums and everyone says its a bit rubbis for playing vides and there is no definative answer. Can anyone help? Cheers
