just like it says in the title I get really poor quality on the SD BT Sport Europe channel. While watching the champions league last night and turning on the Europa League tonight I've noticed I'm getting a 'stream' like quality. It looks like a 240p Youtube video it's that bad. Having a look at other channels (like Sky Sports etc) I get great picture quality so I know it's the channel and not the box itself that's causing problems. My TV is an LED one also so I know it's not the TV that is emitting the bad quality.
Just seems a bit weird and it's pretty annoying to watch a mess of pixels around the players etc.
