That can't be it. The circuit outputting video onto the wire triggers every 1/60th of a second, always the same duration.
There are situations where a player could time things so badly an entire frame has to be skipped, but that shouldn't happen often. And it should basically never happen on a regular DVD player. Any variations smaller than that disappear; whether a frame is ready 15ms before the deadline or 1ms before the deadline has no impact on the output.
