so far is seems that all of the x10 products suck and from what I have read so far no one can get the vanguard software working.
Not So!
Just is more users post to complain then post to state it is working and how they got to that point!
In order to connect to the Vanguard site you need to enable pop ups so Java can be installed
this is need on your PC! you also must supply your user Id from Vanguard inorder to connect remotely
Vanguard only controls the video driver while it is open!
The fact that you can even get a image in any other program indicates it doesn't have control!
Windows only allows one program to use the USB capture device at one time.
Chances are you have the wrong driver for the USB capture !
Do you have the VA11A or the VA12A?
If you have the VA12A you need the updated drivers found here
X10 Drivers:You have to stop All the X10 services from running in windows before you can remove everything!
All that you have stated you have is a camera and the software!
If this is all you have then you are missing some key Hardware for controlling!
I assume you have a VA11 or VA12 but do you have A CM19A and a transceiver? (I think they come with a TM751
)
What is all the Hardware that came with your order?
Supply model numbers!
