Calling all PowerCinema users...

I use VMC on my HTPC 95% of the time, but when there is a HD show playing I sometimes fire-up PowerCinema to get that FreeviewHD goodness.  However I've noticed that over the last month, PowerCinema has become increasingly temperamental...

Initially the interface started freezing when watching TV3 or C4 (TVNZ channels seemed to be fine), but the picture and sound would keep going fine...  Now it locks up within ~10 seconds of opening the application - even just on the home screen.  I suspect it is something to do with the Windows updates and driver updates that have been applied over the last month or so, but am not sure.

Anyone else out there seen this issue? know the cause? and more importantly, know a fix?

Thanks!

PS I have setup PowerCinema to use hardware acceleration as per the instructions posted in GZ.  It was working fine (ie ~5% CPU usage) before this freezing started happening...
