That's freaky about the big brother camera. I haven't been able to duplicate that here and we have no real thoughts about root causes I'm afraid.
With regard to placing a video call, if you don't mind enabling the RoboBrowser plugin (or have it enabled already), you can try the following command:
<?xml version="1.0" encoding="utf-16"?>
<command id="267" name="place a video call to {1}" enabled="true" alwaysOn="False" confirm="False" requiredConfidence="0" loop="False" loopDelay="0" loopMax="0" description="">
<action>
<cmdType>RoboB.Select</cmdType>
<cmdString>skype</cmdString>
<cmdRepeat>1</cmdRepeat>
</action>
<action>
<cmdType>RoboB.Navigate</cmdType>
<cmdString>skype:{1}?call&video=true</cmdString>
<cmdRepeat>1</cmdRepeat>
</action>
<action>
<cmdType>RoboB.Dispose</cmdType>
<cmdString />
<cmdRepeat>1</cmdRepeat>
</action>
<phrase>place a, skype</phrase>
<phrase>video call, vid call</phrase>
<phrase>to</phrase>
<payloadFromXML phraseOnly="False" use2partPhrase="False" phraseConnector="by" Phrase2wildcard="anyone" optional="False">payloadSkype.xml</payloadFromXML>
</command>
If you've already created an end call command (i.e. with the Skype.EndCall action), that willl work to end your video call as well.
Also, if you see the camera light is on when it shouldn't be, perhaps try issuing your "end call" command to see if the camera turns off, and let us know either way. thx.
