I review the forums and help as much as I can, and I work for X10. We also have a number of Community Organizers who can help with problems like this. They don't work for X10, but have a lot of experience with our products, and are very helpful in figuring out problems.
That's a lot that's not working with video on your system. Just to make sure, you are able to do everything you want when controlling things yourself directly from the computer, but are having trouble recording video, etc. automatically using macros? If you use the "Run Macro" button on one of your macros instead of triggering with the motion sensor, does it work? Can you trigger other macros with a motion sensor? How about if you use a remote control?
