Hi guys, not sure if this is hardware related or not. I live in the UK at present but watch live tv from the US. My problem is that sometimes the picture is very pixelated, like if I am watching a nascar race the pixels can't keep up with the background. My os is Xubuntu 12.04 and my computer has an old-ish gigabyte 945 motherboard and a 210 graphics card. Are they too old by todays standards and would an upgrade help? Another thought is could a better router do it? I run it through my tv and the picture is better in 1080 than 720 but still not perfect. Any ideas? Thanks, Rob.
