I previously updated my STB to version 1.6, and had no problem. I just tried to install the update to version 1.63 to fix the choppy audio. It seemed to install OK, but I wound up with smooth audio but no video! I reinstalled, re-memorized channels, cycled through some channels, but nothing helped. I reinstalled version 1.6, and got back to video with choppy audio. Anyone else have this problem?
