I purchased my 1070 in August and am mostly happy with it. I do have the very occasional no-audio problem with my Motorola PVR. It seems to occur only when the source format switches from 5.1 to 2.0 when changing channels. I can't think of an instance where it has occured going from 2.0 to 5.1. I have had one system lockup which seemd to be caused by hitting the mute button while the unit was still initializing.
