Finally got aroung to rebooting to install the new drivers...
PCI-E card is a ati 2400 which doesnt do the acceleration, so its maxing the cpu, but it looks a hell of a lot better than the onboard 3200.
On the 3200 in the onboard there seems to be no proper deinterlacing - constantly seeing horizontal lines bouncing up and down, and things splitting out on panning etc.
The card seems to be deinterlacing a hell of a lot better. What are other people seeing when watcing the interlaced channels on the 780g.
Am using windows 7 7100 and windows media center so I dont have a clue what codec etc it is using.
Also looking at the options in CCC - it seems that the 3200 has less options then the 2400 in avivo - there are 2 for the 3200 and 4 for the 2400 in deinterlacing.
