[QUOTE="KevL, post: 281208, member: 11798"] Many thnks Bolder, your observations give me hope - especially as my hardware is almost the same as yours. I've not tried the Nvidia codec recently. I will try to get hold of a copy. I have to say I'm being very critical in my judgement of picture quality. My TV has bucket loads of settings and only after I spent many days setting up input from my set top boxes did the difference become noticable. Most of the TV setting improvements involved switching off all manner of filtering and picture "improvement" settings in the TV. I now get very good pictures from all sources. HTPC is very watchable but it does lack smoothness. You might be able to get your PVR150 to give a better picture by using ChrisTweaks. This allows you to change the operation of the BT chip and tweak up the video settings. It gives access similar to the settings which used to be avaliable on DScaler on analogue cards. When you say that you get 25fps continuously do you mean that when you do the shift1 (!) thing on MP video it says 25.00 fps continuously? (as I posted mine says 24.xx to 25.xx with about 3 values.) I have not tried ! on HD material yet but I too use the CoreAVC codec. Let me play some more with my settings (at the pc end) and see how I get on.
