Have been enjoying freeview on my HTPC through mediaportal for a little while now, but have noticed that when there is action on the screen, the things moving quickly are very blurry. this happens in live tv and when playing back recorded tv. It doesn't happen when using mediaportal to play DVDs. Picture is fine with slow movements.
I'm guessing it's a hardware problem. Everything I've got is pretty old but works well enough - which part is most probably the bottleneck?
