Yes. I will try to get the aspect restoring correctly.
It probably deserves a new ticket though,
because we have fixed the original problem -
"window is merely offset but not scaled"

What I did was try to make everything visible with the minimum of
code changes, and still allow the other output widgets to work.
I will probably keep stealing bits from patch.part1 :-)

Oops. Forgot to virtualise ToggleAspectOverride in videooutbase.h.
Now fixed in -r25302.

Hmmm. That might be a different problem.
Did -v playback show output like:

2010-07-08 22:24:29.242 NVP(0): Video is 22.8028 frames behind audio (too slow), dropping frame to catch up.
2010-07-08 22:24:29.245 NVP(0): Video is 30 frames behind audio (too slow), dropping frame to catch up.

That sounds like a locking problem. I have seen similar,
but only on Live TV (not from Recordings), and only when
doing machine-gun testing - S Escape S Escape S Escape ...
