Prevent screensaver starting when an application runs fullscreen

Is there a way to prevent the screensaver from running when a certain application is running, in Windows Vista?

I'm asking because I know Windows MediaPlayer does this, but the kind people at Pinnacle Systems seem to have forgotten this, at least in the TVCenter application that came with my pctv100e

As workaround: there is a little utility named flipss.exe which can be used to easily enable or disable the screensaver via a command line argument.

See this links for details: Create Shortcut Icon to Disable / Enable the Screensaver

You can use this utility in a batch file as well.

Use these to stop your screensaver from activating:

Caffine for Mac

Caffine for Windows

I find them useful when watching programmes on BBC iPlayer, or long tech talks on YouTube.

Try ScreenSaver Commander.
It is screen saver manager and it allows you to set a list of conditions to prevent screen saver from running.

You can create a list of conditions in program to prevent starting of screen saver when specified applications are running.
