I have been experiencing tons of audio drops over the past week on my tv using the 3510 pvr. Started 7-10 days ago. The drops range from very quick (1 word) to 10-15 seconds. Seems to be on all channels and happens during both live tv and playback of recordings. In the past when I have had this problem, it has been on one particular channel which isn't the case this time. It is not happening on my other tvs/pvrs.
I have unplugged the pvr a couple of times but the problem continues.
