Yes, I have a samsung full HD camcorder which plays full size in
quicktime without any problems.

It is probably not the avchd .mts format that is being used that is why,
does you camera create .mts files?

On it's way... and indeed, VLC makes a glitchy pigs ear of it. Movist,
on the other hand, plays it smooth as silk. Curious, since both tell
me they're using ffdshow to display. This is, however, on an i5 with
4850 graphics... So lets step down a notch.

On a Core2 Mini 2GHz with 9400 graphics on a 1080HD screen (this is
the Mini that runs my telly), with Movist the picture is smooth but
CPU is pegged at 200% and the sound is gappy. VLC is more of a
slideshow.

So to me this seems more of a specific codec fail than anything due to
the Mac - if there's only a decent codec for Windows, then you're
stuck with using Windows. Shrug. You gets what you buys.

There do seem to be an awful lot of mentions on the Web along the
lines of "How do I play these?" "How do I edit these?" and quite a lot
of "How do I convert these to something useful?"...

Macs have had `proper hardware acceleration' since 1984.

What they've usually had is more of it and better of it than the dark
side competition - but also *different*.

And what's always proven true is that the areas in which Macs beat the
dark side, those who like the dark side ignore; and those areas in which
the dark side beat the Mac, those who like the dark side use as a stick
to beat Macs with.

Why oh why is anyone paying attention to this troll-advocate?

Perhaps try something like VLC? I've got an oldish (C2D) Mac Mini that
plays most things fine.
