I was watching HBOCY (307) overnight and would get Error 004 popping up on-screen every half hour or so for no reason I could find telling me to channel up, channel down or to hold the power button for ten seconds. I hit "Cancel" once and the message stayed the same, then upon hitting "Cancel" the second time, the channel returned. I looked on the DN site and it mentioned this is a check switch error, but my switch tests pass with flying colors and the error box I get says nothing about the switch, just to change channels. It's only happened on HBOCY so far, and I've never seen it on any channel before getting the L617 software. Is this widespread? An issue with how HBOCY is being uplinked?
