Is there any method I can use to show a custom Icon (alpha blended) over the video view (TV or recording)? This should be used so that the user can click on it and start an addin.

I can manage to do something like it by calling an mcml page that has a Video Tag in the background. This shows my icon perfectly over the video. But this way MediaCenter will loose the time overlay and the scrubber bar. So ist there some better way? Or are we stuck with using dialogs?

I already feared that...
Well the time overlay shouldn't be too much work...

Have a look at the "PanelSession" class in the SDK documentation.   It's not designed for what you're trying to do, but it might work (Windows 7 only though).

Thanks, I'll have a look at it and write if it works here. Unfortunately I'll have to support Vista and XP too (XP getting a completely different UI anyways).

 RZiller,

I jacked the overlay scrubber bar from the previous version of Internet TV and modified it for my needs. Worked well.
