I have the 700bt and get my videos to play through my usb flash drive but they range from very small to small. none of them are full screen. How can I convert them to get them to play full screen? Is there a program to convert them or a setting? I also have an external dvd player on the way to add on to it and was wondering if it will do the same thing. Thanks to everyone that can give me a hand on getting these bugs worked out.
