Brad - I read another post that talked about the 30 fps spec. Video size is 320x240. I notice that I only get the VideoSize error when I push the file to the emulator after starting my app. If I restart the emulator, then I get the prepare failed error, which is probably the actual issue.
Dave - Not sure what the frame size is or how to tell, sorry, not much video experience. I was guessing that I only had G1 specs. I can't seem to find anything definitive about the emulator. Unfortunately don't have an actual phone right now. I'm creating a demo for my boss, and will hopefully get one out of it if I can demonstrate it has some value. thanks for your time guys.
