I'm using a 256mb video card (not sure of the exact specs) but in the
Adapter settings in Display the max resolution is 1920 x 1200 at max color
which I'm using presently. 720p stuff seems to play ok (somes some
digital artifacts when the camera pans) but 1080p stalls and freezes. The
CPU is a 1.8ghz e4300 Core 2 Duo. I'm using a genuine Intel motherboard
which unfortunately doesn't support overclocking. I'm tempted to change
but only if I can play 1080p. I don't do any gaming. I want to buy a
hi-def video camera but I need to be able to see what I just shot!

You don't give away too much detail on what your gaphics card is but High
Definition 1080p video requires a pretty good card to display properly (your
graphics RAM meets the recommendation but *only* if it isn't shared or part
shared). Your processor is a little bit borderline as well and the
combination may stutter depending on what else the processor may have to
service. The fact that you don't play 720p perfectly suggests that you are
definitely struggling even at that resolution. You also don't say which
codec your video is coded in, but the MPEG4 codecs require significantly
more horsepower to decompress than the MPEG2 codecs. All the 1920x1080 HD
video cameras that I am aware of use the very highly compressed H.264 codec
which requires a lot of processor power.

If you are planning on editing the video on your PC, then your processor is
totaly inadequate as virtually all the decent editing packages require a
Core 2 Quad as a minimum to edit 1920x1080 video. Anything less, just won't
work at all. They also only work with certain graphic cards as they use the
GPU to produce the transistions and effects.

All HD cameras output standard definition video so you can see what you
shot - just not in great detail.
