My VIP 2250 STILL drops audio AND reboots/freezes. Posted on another thread in the forum but still no fixes as far as I know...unless someone else has any advice.

CAT5 to main TV (2250 DVR) connected to TV via HDMI

Coax to other TVs (1200 series STB)

New black 2-Wire gateway.

All connections replaced and tested by techs.
