yep - then doing manual tune for each of the 5 multiplexes as per instructions
all channels show up, then 20 min or so later none are watchable ('the channel is scrambled or not available' message comes up) except for channels on the multiplex the box is left on during that time. As long as i stay on that channel i can still record from other multiplexes and watch them back ok, but can't get live tv to show on them
