It confirmed that it is M-JPEG.

That made a huge difference; I now have smooth playback at full-screen
with the CPU load under 40%.

I'd overlooked that as I'm in the same boat as you. Mixing 30p with
50i doesn't sound like fun. Since my target destination is not TV, I
hope I have a few other options available. I might just stick with my
camera for now for both stills and short video clips. I already have
a lot of things to learn so maybe I should curtail myself a bit. I'm
new to photography also, so I'm getting to know my camera, Photoshop,
then there's the animation that I want to do, video editing,
compositing?
So I can render the animations @ 30fps so they'll sit easily with the
AVI's that my camera shoots. By the time I'm ready to go deeper into
the video side of things, hopefully there will be a consumer 720p PAL
camcorder available. Can I then just simply re-render the animations
at 25fps so they'll match the HDV footage?
I'll still have the issue of mixing 4:3 and 16:9 footage, but I've
accepted that, as there isn't currently a camera that takes widescreen
format stills that appeals to me. I imagine that more cameras will
add widescreen format capture in the near future! The Panasonic Z20 &
Z30 currently offer that in the ultra-zoom sector, which is what
interests me; I have a Powershot S1 IS.
I'm wondering if I'll be able to digitally project my 30 fps footage
using a PAL projector. I imagine that since I will output it directly
from the PC using a DVI connection, that the only issue will be
whether the projector can handle the resolution and refresh rate of
the PC output.

That seems to open a whole can of worms : )

What surprised me was that even the sub £100 NLEs now support HDV or
in some cases there are imminent releases pending.
I'm going to start a new thread on one of the video newsgroups to try
and determine which applications suit my needs. It's the animation
and compositing side of things that has me in the dark. After Effects
sounds like it might be the daddy, but, it is horribly expensive and
there is no consumer edition (Elements). Hmm.
