[PROBLEM] CEC disconnecting when I play a video

[Kinnell]

When I start playing a video, CEC disconnects:-

Code:

...etc...then I stop the film with the iphone remote and...

Code:

20:01:24 T:2966717504   DEBUG: CecLogMessage - << Recorder 1 (1) -> broadcast (F): active source (1000)
20:01:24 T:2966717504   DEBUG: CecLogMessage - << 1f:82:10:00
20:01:24 T:2966717504   DEBUG: CecLogMessage - << Recorder 1 (1) -> TV (0): menu state 'activated'
20:01:24 T:2966717504   DEBUG: CecLogMessage - << 10:8e:00
20:01:25 T:2966717504   DEBUG: CecLogMessage - >> 01:8d:02

... everything is working again

Update: It seems to be video mode changes which are causing the problem. If I change the screen resolution in Settings, CEC also stops working.
