before that, all video would look normal, and most video would playback with only minimal framedrop.

now, most only display like this
this is with mpv, and its output is something like this - looks ok to me???
but the problems are abundant with all video formats and media players (mplayer too, and i spent a good while playing with VLC's settings).

i tried:

downgrading kernel back to 3.10.105 version == downgrading packages linux*pine* to version 5.31.
it helped a little - i was able to watch a few very old & lo-res episodes.

then i found this: Video playing will break on sunxi legacy unless adding cma=96M to kernel boot parameter, so i undid the downgrade and added that option to /boot/boot.cmd & recompiled, after which i could see those 96M in 'dmesg|grep -i cma' (was 64M before).
but it did not help at all, the situation was just as bad as before the kernel downgrade!

what to do?

one other thing to consider is different video playback apps usually use different methods and different combinations of video drivers and native files to playback so what happens is  if you install 3 different playback systems you run a strong chance of creating combinations of differing files as well as versions of the same file that could possibly screw up one or the other applications that may persist even if you attempt to remove one program prior to installing another. it seems worthwhile to try on program on a fresh install, best to use the new snap system which helps isolate each program to its own space.
