Ooo, never knew that. 

I think I'll have a go at getting the quickones site up with proper links to the videos 
and some FAQs about playing them. I'll put tips like this in there too.

I am using xvidcap at the moment which can capture in any one of a number of formats. I 
am currently using MPEG2 as the capture because I know I can a) edit it in avidemux, and 
b) convert to OGG later with ffmpeg2theora, oh and c) it doesn't place a massive load on 
the machine to encode to MPEG2 whereas encoding to OGG murders the CPU.

It does, and that's one reason I now don't use it. Once you have an OGG it's not that 
easy to convert it to other formats. Having the "master" as MPEG2 is a lot more flexible.

Nothing I've found, nothing well anyway.

Thank you.

Are you using the kqemu (non-free kernel module) accellerator with qemu? It makes a 
tremendous difference to the performance.

Or you could install Ubuntu on another machine and remotely control it via VNC, and 
record the VNC window. This has the advantage that the processing of doing the demo is 
done on one computer, and the recording processing is done on another. This means you 
don't have one computer doing both, and getting swamped as a result.
