I am still on 1.02.20 and just went through London DSO and I have only just started noticing this:
Press guide then exit the box goes to blue screen with the above message instead of returning to viewing the channel.
That's presumably the MHEG application that loads from the new CONNECT channels and it's stuck somehow. I'd make sure you're on a normal channel then try a full shutdown/power cycle if you haven't already.
That's what it was. Thanks. How did I forget the classic turn off/on ? With hindsight I noticed the problem was that turning off I still had the blue ring on which meant that the Connect was still attached somehow. Thumbs up for redring. Only a restart following a recording programmed via webif cured it, before I tried the rocker.
Warning Notice : Do not touch the Connect channels. I deleted the f*ers now.
It's the racing channel that causes it - found out a few weeks back.
I pointed it out to Barry on the myhumax.org forum and he advised to leave the box off for 15 seconds if it's connected to a network to get rid. Also he advised to delete all the IPTV channels as they are not supported!
Let's see how long that line lasts!
