I've been able to do a hot unplug of the cable to reset handshaking to re-establish HDMI to DVI connection up until this update. Is it time to give up on Roku, or has someone found the magic trick to keep things going? Every time there has been an update since 8.1 (IIRC) I've had to unplug to reset the connection, but they've managed to mess it up beyond redemption this time. Help?
