Robert,

With the latest ffmpeg and x.264, the "hq" preset you use seems to no
longer exist.

I believe the nearest replacement is "slow".

Anyway, it still doesn't work for me, something to do with your
surround sound detection?

Editing the script to force stereo works fine - since 90%+ of my
content is 576p with stereo audio, I might just keep two different
versions of the script.
