i have a actions semiconductor mp3 player (one of those cheap chinese ones) and i have an oilsky D26 mp3 player. the oilsky plays all three of the test .amvs from the chinese one, and the chinese one plays the test video file (ALL DX.amv) from the oilsky mp3 player. but i can't get both of them to play videos that i made. i tried making them the suggested size, no luck. i tried to convert them to .amv, also no luck. why does it play the test ones well but not the ones i made???
