So I've been messing around with my new R4i Gold and I have some movies on there such as Frozen and some of my favorite seasons of South Park. When click play, the screen goes black and freezes for Frozen. When I do it for South Park, the video plays for not even a second and then the green light flashes like it is closed. It's in DPG, but could it be in the wrong format of DPG? Thanks Tempers!~
