I have not checked if it shows output signals but it also says that there are no modes (I had expected at least PAL and NTSC):

But if there is no detection, is it possible to turn it completely off (our device shares the TVout with the headset microphone input so that we need some control to switch between both)?
Would xrandr --output None-2 --off turn off VENC?

Ok. Perhaps it's broken. I'm quite sure VENC worked at some point. My beagle-xm has died some time ago, and they are not sold anymore. That was my only VENC device... =(
I have revitalized my BB-XM (with external LCD) and there I have the same:

What I have not tried is mainline for beagleboard. So I can't 100% exclude that we have something in our Letux kernel additions that creates this effect.
For cross-checks on Pandaboard and BeagleBoneBlack I have to update the µSD cards first to Jessie.
