XDA peeps have fixed the details so videos are sharper but they can't (and won't be able to) fix the metering problem whereby the hardware itself is the cause. It has never been fixed by HTC or any custom ROM or mod on any HTC device to date and I can't ever imagine it being fixed on any future phone either because HTC don't really care.
No, but the metering isn't all that bad, it's the bitrate being low causing the juddering that's the problem.
Ultimately it will look more or less the same as the rest when being viewed on the phone itself and that's the only place I'd look at it. It doesn't excuse it though. Very odd.
