It seems the problem is with the LG (42LB650V Smart 3D 42" LED TV ) Now TV app only.
I have Roku box and its plugged into a 55" samasung TV and the quality is much much better than the LG. The Roku connects to router as wifi as well as LG. I thought the quality will even deteriorate on larger screens but Now TV app on Roku is doing remarkably well.
My broadband speed isn't that good 3.5Mbps and on LG Now TV when pused displays 3100 as quality. Roku box dont show any number when paused. Also i note the BBC iPlayer also streams fine HD quality on the LG TV even at my low bradband it doesnt judder, occasionally it buffers but not often.
So I can only think its something to do with the Now TV app on LG TV.
All my tests were done while no one else using my internet and only one device was streaming at a time.
Any thoughts please?
Thanks in advance
