IMPORTANT NOTICE:
I quoted myself because I want you to be aware of a possible issue if you use the quoted workaround…
You can disable CB video services using the aforementioned workaround but please know that some users have reported failures with CB maintenance release upgrades because of the moved/renamed video files. It looks like you must remember to replace/rename the video files back to their original state or the upgrade may fail.
I’m not sure if this causes failures to major version revisions but I do see reported issues for maintenance release upgrades.
Who knows if other issues occur because of these “self reprogramming” actions. I recommend not to do them but… I’m not the computer police so alter at you own risk.
Of course this all would be moot if a “real” preference option was incorporated. 
Regards.
