Actually, I stated the problem inaccurately. The setting is retained,
but Amazon Prime Video ignores it if I power cycle either the AVReceiver
or the Fire Stick. To get APV to respect it again, I have to set to a
specific display setting other than auto, then back to auto and (which
unsets the "Match frame rate" setting) and then reapply the Match setting.

I forgot it was1440x1080. The BBC went through a phase of using that
res, but later gave up on it. The higher bit rate must have been my less
than ideal choice of parameters for transcoding.

Sadly I don't have to look for it. If it's not perfectly smooth, it
looks terrible to me. Possibly not helped by my TV having no smoothing.
