I have 4 TiVo mini's in my house. On occasion, I have the following issues with one or the other, so its not isolated to one bad Mini unit. 1 - No sound at all - need to standby and turn off TV - then turn all on again and it works - happens 2-3x month. Might be an HDMI issue 2 - Turn the TV on and Mini out of standby = blank screen, I then unplug the Mini and it reboots and everything is good - this tends to happen if I haven't turned on that Mini for several days Now I am not sure if all of this is tied to some sort of combination of using switches (blank screen requiring reboot) on all units (green) and/or HDMI (sound loss issue). Any feedback or others experiencing these issues?
