i have an avic z3 im trying to burn dvd from videos on my computer to play on my z3 i check the owners manual it say it plays "video format" what does that mean? mp4? wmv? i tried burning it in different format but when i stick the dvd in, my Z3 displays "error". I wonder is there any software recommendations i can use to burn dvd or specific formats others have success on.

thanks in advance
