Hey Nick, the external monitor output as been the same for years.i think it's on 1024 x 800 or so nothing crazy high output. I don't have the problems running the videos without activating M.E. If I use my video's as you would mp3 style it's fine. I also don't notice it happening if i activate Serato Video. It only happens when i use M.E. The only window i have open besides the main output window is the control window that has the effects options and cross fader on it. I have that at the very bottom in the middle. It covers the bottom 3-4 songs. Nothing else from the program is open. The jittery issue happens when i'm just playing the video, i dont have to be doing anything crazy to make it happen, no scratching no beat mixing, it just happens if the video is playing. I don't know if this will make a lot of difference for a solution but it's not jittery if I don't have the output hooked to a external monitor or TV. I tried hooking it to a computer monitor and flat screens etc. and the wave forms are very shaky. Do you think my 4 GB Ram can be causing it, maybe i need more?
