mystic swap the two wires going into tuners ,that is connect wire that is going currently in tuner1 to tuner and vice versa and also if u have another box connected to other tv keep it on stand by mode. try manual download it will work
finally firmware of my HD DVR updated to release 105.
I have not checked for all changes but I noticed two changes, record / series recording option is coming when pressing (R) button. Second one is good one, it will give you chance to set volume level for STB. :tup
