Thanks for the couple of suggestions. I briefly drifted into Ubuntu land and came across a couple of tools that use OGG natively. It is not a perfect solution but I can use Istanbul (a GNOME screen full screen recorder) to record the visual element as a theora file. Then use any OGG capable program to record the audio. Finally using oggzmerge to merge the two OGG files into another OGG file that combines the audio & video. If anyone else is interested the two tools can be found at the links below:- http://live.gnome.org/Istanbul http://annodex.net/software/liboggz/ Thanks again Lee -----Original Message----- From: Bryan J.

Just FYI, it's more than just CPU usage. A "raw" analog NTSC video stream (I'm assuming NTSC) is over 30MBps. Considering it goes from card to memory to disk -- possibly all over the same, shared 32-bit @ 33MHz PCI bus (133MBps), it saturates much of the PCI bus, so frame loss is probable. So having at least an MJPEG compressed stream reduces that far more to a measly 1-6MBps (depending on compression ratio), and MPEG-2 typically to under 1MBps. You usually want to capture MJPEG if you are going to edit the video (especially if you need high quality, individual frames), or MPEG-2 when you only might recorder/cut it or possibly convert it to a lower-quality anyway. -- Bryan J.
