Ultimately what I want to do is watch all TV though the media centre so that we get a "mysky" type experience being able to pause rewind etc + watching the Freeview HD versions of 1,2 and 3. However as it stands the quality of telstra via the media centre is just not good enough. It looks quite a bit worse then the feed going to the TV direct even though the media centre is getting s-video and the TV is only getting composite

So my question is. If anyone is using the PVR-150 card just how good is the capture? Am I expecting too much from analogue capture devices? I know that the 2200 has some technical issues with capture but I don't want to buy a 150 and then find it is not significantly better then the 2200.
Or is there a different card that is more suited?
