Script Summary: Enlarges the embedded player
For users whose graphics cards produce choppy or flickering images in full-screen mode, this crude workaround resizes the Flash player about 240% (in each dimension) to 1200*800 pixels. (Full screen on my display would be about 60% larger than this.) This gives me flicker-free, high quality video at an acceptable size.
At the moment, this script does not affect the NYTimes front page or even the main Video page menu. It kicks in when you select a video. I wanted it to be less intrusive while I am still developing it.
I haven't yet gotten it to zoom automatically to its full size. My guess is that this is because the Flash Player size is specified during the interaction between NYTimes and Brightcove. If this is so, then it all happens before the load-event-listener triggers the Greasemonkey script -- which is to say... the solution is way beyond my skill level.
After the page loads, right-click in the gray area and select Show All. (I sometimes need to right-click, open Settings, then right-click elsewhere to open the context menu that offers Select All.)
