The Dell Zino HD arrived and it's working as a MCE. Freeview plays great, with no stuttering, but now and then there are some green blocks or old frames flick on screen.

I will obviously check the drivers - looking for some new ATI drivers, but it also comes with Cyberlink PowerDVD installed, so I am not sure which decoder is being used - Windows 7 or PDVD?

Is there a program that will list all decoders in the system and which ones are active/default?
