In have just purchased the new unit and overall it is excellent however one feature really bugs me… when listening to the radio a digital clock appears and moves round the TV screen ( very hard to ignore). It can be removed for a few minutes but pressing the info key but it soon re-appears.
I have two alternative audio feeds from my PVRs: One direct to my AV amp and one direct to my hi-fi stereo amp. These allow me to listen to the radio (usually a radio recording) without needing to have the TV set turned on at all or I sometimes have it tuned to one of the rolling news channels with the sound turned down. You may want to consider that approach.
