Yeah, and now Flash 9 is out for the Mac, it's just us Linux users that are
left out.

Indeed. There's a bug report to put back the feature that used to be there
which allows for two-stage record then encode. The author is quite active in
this area so it's worth keeping an eye on the Istanbul home page.

You don't need two computers for that. You can use one computer and just
spark up a vnc session under another user with vncserver. But it's probably
better with two computers because you have the processing overhead of
recording on one box whilst the demo is on another.

I gave a talk last weekend at the HantsLUG meeting about recording the
screen to video. You might want to have a look at it.

You can download the OGG/Theora video and the WMV from the page below.

Alternatively you can watch via google video.

Either DemoRecorder or xvidcap get my vote. Xvidcap is neat because you can
record any window direct to mpeg video.

Cheers,
