 I have increased the bitrate of the video to 1000 as it does not seem to affect my CPU load appreciably. You may increase it more if you like, but 1000 kbps H264 actually provides a better quality than 10000 kbps MPEG2. The CPU load difference on my computer is 90-95% versus 60-65%, so if your CPU is too slow or you need the extra capacity you should use MPEG2. In my case the key to avoiding jerky video was to reduce the size of the streamed desktop area. I have increased the bitrate of the video to 1000 as it does not seem to affect my CPU load appreciably.

 +**Tip**: If you are using Google Chrome the zoom step is very large and cannot be changed. There is, however, a very convenient extension called zoomWheel, that will let you zoom with your mousewheel in steps down to 1%. You can add it to Google Chrome with one click at http://www.chromeextensions.org/appearance-functioning/zoomwheel/. With this extension you can always make your video appear with the size you want.
