Thank you both - Moritz and Andy.
Moritz for the insight into the filter (I kinda figured that was the
underlying process but needed it to be confirmed) and Andy for the
Mplayer's hiccups. I suppose I should ask a supplementary question.
Given that a file might switch from yuv420p to yuv444, is there any
great significance to domestic equipment? I see the failure of Mplayer
to cope with the change but can this failure also apply elsewhere?
In a sense, should one aim for yuv420p for compatibility?
