Very choppy Google TV channels

This is infuriating. I am having the system as Thanksgiving and typically worked well. Did experience alike issue through video where it blinks for a few minutes but it just occurs sometimes. I have normally been equipped to clear that up by modifying channels to the non-high definition channel as well as modifying that back. After the update the sound goes out after each few minutes. This does not occur when only using sound on TV but only while using bose sound system.
