Oddly it does seem to happen during the action sequences like the video processor is overloaded so it stalls to catch up but when it restarts it might be ten or fifteen minutes further into the movie than where it stalled.
Sounds like the periodic copy protection check is failing, thus forcing a new HDMI handshake, and the projector is not reacting well to that. The idea that the projector resets its menu sounds to me like the projector thinks a new source device is talking to it, and it is trying to remember menu settings per source.
The copy protection check happens roughly every 10 minutes. Normally it happens in the background and you notice nothing. But the check LIKES to fail, and if it is unhappy you get a new HDMI handshake which will mute video for a few seconds.
The fact that this is happening with DVD and the Internet apps but not with Blu-ray or your cable TV box suggests to me that your HDMI cabling is unhappy with 1080p/60 video but is OK with the lower bandwidth 1080p/24 (Blu-rays) or 1080i/60 (cable TV).
(If you have your Cable TV box set to output 1080p, then it may simply be the channels you are watching are not Copy Protected.)
To test if this is what is going on set the Output resolution of the OPPO to 1080i and see if the problem goes away. If it does then you need to upgrade your HDMI connection. This could be as simple as reseating all the HDMI plugs back in their sockets.
If you have Deep Color turned ON, also try turning that OFF to reduce bandwidth. Again if that fixes it then that points to your cabling.
