For the past week I occasionally lose audio on some channels. Last week it was MSNBC (HD) and tonight it was TBS-HD during the NLDS game. Had FiOS installed on 8/3/11 with new Cisco DVR STB. The only way to restore it is to power cycle the box. The upstairs STB (non-dvr) works fine and has audio when I lose it on the dvr.
Any help?
