Holy sh*t!!! I just started looking at doing a retune to kill this off, starting with a schedule backup via the WebIF (custom software). Except the WebIF showed no schedule to back up. I though it was a malfunction, so I went Guide >> Yellow... no schedule! Thank heavens for the automated daily backup. So what can cause the schedule to evaporate? A retune. Check tuned channels.... 1: BBC 1 Wales??? ITV1 Wales on 800? WTF? It looks very much to me like the Hummy has acquired the ability to force a retune whether you like it or not. Possibly it puts a warning up on screen, but my HDR sits turned on all night as a media server and the screen isn't being looked at (isn't even on). Fortunately the auto-backup taken about 2 last night was pre-retune, so contains anything I might have tweaked yesterday. I now have to do a manual tune to get single-region West, and reinstall the schedule (again). YOU HAVE BEEN WARNED Perhaps this is something "we" can kill off, like the OTA check.
