hey all, I know theres post and posts about this, i read them all, I downloaded a program 3gp_converter , various versions. But for some reason it wont let me drag and drop any videos in there. Im running windows vista, that why? I converted a 3gp video using another program and tried it on the 903 but just a black screen. Ive been trying all day to get videos to work but nooo. can anyone help ?
