run autogk as service with firedaemon

I work in a computer lab at school with lots of P4 dell computers (nice:). I want to run autogk as a system service with low priority to process lots of videos in the background while students are still able to log on and off and use the computers. They should not know that anything is going on. The system I tried it on was running Windows XP pro and I had admin privlages. I installed autogk as a service in Firedaemon Lite and setup to interact with desktop. All this works good but after i start a encoding a batch, I need to log off of the computer to let other users use it. When I log off the computer- autogk gives a message "please abort jobs before exiting" and quits after I log off. It should not quit because it is running as a system service but because windows broadcasts logoff messages to all open apps, and autogk doesn't handle the broadcast right(i got this from a faq at ), it quits! I see two possiblilities of making this work: 1. AutoGK gets fixed to allow it to be run as a system service. or 2. I can setup AutoGK to NOT interact with the desktop. This way it would not be affected by logoff messages. But I would need to pass command-line args to it to start a batch. Is this possible? Can I save a batch in AutoGK and invoke it at launch with command-line args? Is there a program like autoGK or GK which supports being run as a system service?

What an appropriate usage of school resources :) If I'm not mistaken those are not designed for personal usage like this... Anyway AutoGK requires GUI to be open as job queue is actually stored in the GUI elements and I have no plans to make CLI version of it. I doubt video encoding reached the status where it needs to be run as a service, therefore there are probably no programs which do that.

oddly enough, i know that in a "neighbouring" university near where i am, has a media centre which records lectures and tv shows for its students and staff, and all the captures are encoded up good for streaming/archives. though, they do have a cluster for all this, i am not sure what sort of codecs they use. i don't think its too far away that video encoding does become a service on a system for the average joe.
