Yes. My apologies for missing this change. It meant that what I wrote about
the 'flash mode' results yesterday was wrong.

That raises a question about the optimum fallback when a mode isn't
available for a given file.

In some cases when I tried 'hvfhd' I was told that wasn't available. (This
is for some of the 'section' files from Proms.) I was then wondering about
what 'sequence' of modes would be best for finding the 'best available'
version. (And also dodging problems like the current ones.)

e.g. having something like  --tvmode=hvfhd1,hvfhd2,hlshd,...

I've not yet tried the lower res hvf so don't know how it compares with the
others.
