I've tried a few times to refetch to check that. Tried it up to 10 days
later. But for each Prom file I've tried this on I get the same results.

I've also tried experimenting with supplier exclusion without getting a
change.

In the past for non-Proms trying again did sometimes get a better result.
But it doesn't seem to help here for the Proms.

Ah! Now I've not tried hls. That's worth an experiment. Can I just
substitute  --modes=hlsvhigh for tvmode=best ?

This morning I wrote a simple drag-and-drop ROX app to let me use ffprobe
so I can tabulate the file details.[1] Aim to collate results for some
example Proms to see if I can recognise any pattern. But if someone else
finds they can get *all* the Barenboim/Whitacre files as 1280x720 it would
show immediately that I'm doing something wrong/sub-optimal.

Cheers,

Jim

[1] One sad result is to see the audio bitrates and how much lower they are
than for Radio 3 or DVB-T2 ! :-/ Oh well, at least I've been capturing
those as well for comparisons. ;->
