the jumps maybe because its at 30fps, PAL is 25fps so you get some drop framing.
the HD quality looks very good, although the audio isn't crisp
one issue I believe is streaks caused by hot spots, ie the sun, light reflecting off water.
also I don't believe you have control over the focus whilst in video... ask an owner
It's possible that there is a 30/25fps problem but with HD sources the whole NTSC (never the same colour) incompatability has all but gone. I think all TV's now can display both 50Hz and 60Hz sources.
Yes, the audio is crap, but I can live with that for now - I'd only be wanting a bit of background atmos rather than good quality v/o's.
Vertical streaking on highlights is a fault of most domestic video cameras (I have a Panasonic GS500 3 chipper and it suffers from the same fate).
The autofocus does work in video mode, but is a lot slower than a dedicated video cam so allowances need to be made for this in editing.
As I said before, the video aspect of this cam would be secondary to its stills capability, but a benefit still worth having - especially for a little over 200 quid!
