'WATCHOUT-codec for stable WATHOUC playback-2012.pdf' has a look at this information.
Frame-rate
23.98/24 fps is a very poor choice, for clips intended for 50 or 60 Hz displays
At worst, will result in severe sutttering of the video content.
23.94/24fps is a poor choice, because WATCHOUT did not support 2:3 pulldown?
Does it have other symptoms in addition to stuttering?
(For example, halt Display server.. lost video signal..etc)
