I've now updated the guide for eventTrigger since the TellStick Pause plugin isn't compatible with the latest version of MediaPortal any more.
I can also upload a more advanced EventGhost configuration if there's some interest. It should disable incoming phone call triggers if there's no video playing or if it's on pause. It could also handle this scenario:
1. A phone call is received and the video is paused.
2. Your friend is tired of waiting for you to finish talking and starts the video by remote.
3. When you hang up you wouldn't want to video to pause again.
Sure it might not happen regularly but you never know...
For my automation I use HomeSeer this includes X-10, Z-Wave, LightwaveRF and IR as well as room client MediaPortal control (using my Automation/Automator plugins ).
I'd like to be able to use something like the open source around - trouble is most, if not all, isn't really up to scratch.
