Fix AVI framerate

Browse Source 
MAME was setting up AVI before devices have properly launched, so default 60fps was used, which resulted in skipped frames in the video if machine's framerate is above 60 (btoads), and presumably duplicate frames for machines below 60fps (haven't tested).

Now every frame that is generated is also present in the video.
