Actually, I now think it might be something the Beeb are doing...

I've just run through my archive of all series 2 of Simple Suppers
mp4s and remuxed to mov using the same params that get_iplayer uses:

for %F in (*.mp4) do "P:\Program Files
(x86)\get_iplayer\ffmpeg\bin\ffmpeg.exe" -i "%F" -vcodec copy -acodec
copy -f mov -y "%~nF.mov"

Using my original r25557 ffmpeg the last 2 report the brainfart
message and all are watchable

I repeated again using r26401, no brainfart messages and the first 5
are watchable but the last 2 exhibit the green/pink band and
"shadowing"

So it seems that some time between 2/12 and 8/12 (these are the dates
I downloaded the last good and first bad eps) the Beeb changed
something with their HD encoding which is causing this problem.

I haven't observed this issue with vhigh content.

Linked are the two outputs (sorry they are copies/pasted from the
cmd window - I can't figure out how to pipe a for...do loop to a text
file)
