@Ahsjejdkd your post has been moved to the Samsung forum. You may get more help here.
I am on adsl of around 3mbps; some NowTV progs stream at just over a 2k speed,
but when I select another prog, (immediately after finishing 1st prog) it comes in at just 1010, which is still viewable.
Do some progs that are more popular suffer from some sort of contention?
