Post:

Dan,

I would really like to second Steve. To get a camera with a composite
or better a S-VHS analog video output and directly connect it to the
projector is by any means better than the multiple conversion path
through a PC. In the cases you need to display edited camera images
from a camera software then you should definitely go for a solution
that connects the camera by a Firewire link. That way you will be
able to nicely control the camera from your PC in addition to good
video streaming from the camera to disk or vice versa. Actually
Firewire was designed by Apple and optimized for video streaming.
Firewire was later standardized be IEEE to become IEEE-1394.

Because the MS-driven PC industry did not want to reward and adopt
the IEEE-1394 standard mainly because Apple demanded a minor
copyright license charge they instead hyped up USB for video
streaming, something it was not initially intended to do. As a result
most PCs now have something which is technically not really adequate
for video transfer. Oh well that's the way things evolve when most
customers do not really evaluate what they buy. Maybe they are simply
not capable, because they never really cared about physics and how
physics is technically applied ;-). Anyway, I drifted off again...

However, I really do hope Steve Jobs will make it through again.
Apple won't be the same anymore without his creative mind.
