I wanted ME 1.2 because I work with "online video streaming". On my program that i use there is an option button that detects any video display from any program, but unfortunately the display on ME 1.5 is not detected, not sure why. Instead I use the Serato Video SL program which does detect a video "display" on the program that I use. I found ME 1.1 and tried it out with the program that I use, it worked!!! BUT it doesnt allow me to use some of the cool features 1.5 has, specially text. Note: If you put the display on 1.1 and 1.5 side by side you will know what Im talking about.
