Yes, that's my experience too. Haven't found a way to improve matters.
Just check updating with flash player 11. Some improvement is there what i felt. And please dont forget to take backup of 10.1 flash b4 updating
Thanks for the replies. The first thing I did when I got the box was install Flash Player 11. So not sure how it would be with 10.1!! It is still unwatchable with the embedded flash streaming. Wonder how YouTube does it? I am reluctant to believe it is a problem with the box as both YouTube and the embedded flash sites use Flash Player. So why should there be such a marked difference? Still suspect a software firmware issue in how it is handled. I am planning to upgrade to latest U110781_1109050_HW and see if it makes any difference.
