you are able to use other codec, like lav and I don't have micro juddering. even with boblight you should have the same problems.
In my opinion there are some possibilities for you
1. xbmc with windows and fullscreen windows - juddering and tearing
2. xbmc with windows and true fullscreen - no or just a bit juddering and tearing, but no ambilight, atmolight ot whatever you will call it
3. xbmc with linux and boblight - there is a server/client solution, but that's all I know
4. mediaportal and xp (only 32bit is supported) - not juddering no tearing, at least it works for me.
Sorry, can't help with this.That is why I asked what is meant with "GDI live mode"? Is this just the "live" setting instead of a fixed colour in atmowinx software?
Does the directshow filter of atmowinx help in any way? there is a readme how to install and register this filter e.g. for VLC.
