Thanks for replying, I get an enlarged screen of what appears like a scrambled satallite tv image (lots of random green areas with a few other colours mixed in). I could send you a screenshot of this if you like - will have to do this tonight though.

Hi, the full screen view on tilt viewer pro doesn't show on all the PC's i've tested it on. Is there a codec I need to install or something (it's not flash player, the latest version of this is installed on all).

If somebody knows please could you let me know what needs to be installed so I can point users to the fix?
