Hi lookandsee. This is a good question to ask but instead of starting a new thread you might want to go to Arcade Issues HELP at the top of this Forum page. Hsn does regularly read all questions and concerns from members and do their best to help and or answer you.
Buffering is caused by a slow or busy connection. It is the streaming trying to catch up.
May I suggest clicking on the stop button for the video (located on the bottom left of the streaming video box). This should eliminate your problem. Stopping the video only works on that page. When you access another game, the video will play again.
