Seeing reports of this posted in other places, and witnessed it myself just now.
Example, watching BBC2, and unit changes to BBC1 by itself, and/or text menu displayed, changes to BBC1.
Something amiss on the BBC mux? which is affecting 9200 only, my 9150, and 9300 do not appear to be affected so far.
Easy solution to keep watching the BBC channel you want, press pause for a few seconds and watch in timeslip mode.....subject to any timers you may have set of course.
Humax Towers are aware.
