Re: Tentacle and Witches
Looks like they use a specific overlay output and/or hotkey disables. For example with media player classic you can choose DirectShow Overlay Mixer, using print screen will produce a black screen instead of what you're actually seeing. This is because the video is actually "on top" of what the screen capture can see.
Using a virtual device would solve it, as the overlay mixer would be inside the device, and the screen capture device would be on top of the virtual device. As you said (Never tried this myself), the DRM preventing such a device would not make this a solution.
Basically what it comes down to is:
1. Remove the DRM, which is probably the hardest.
2. Have the DRM think it's not in a virtual device through various means.
3. Find a way to have the overlay be ran in a device that can output it into a video that actually can be captured. Think of having VLC run MPC in the overlay mixer.
4. Probably the best, if feasible, run the video in DRM, have a second PC connect to the first one (Remote view, doesn't have to be control) and record the video on the second PC.
I have no clue if the DRM prevents the remote control to work, I would think not, but not surprised if it did with my experiences with Starforce. You seem to know a bit about DRM wintermute, you know of people trying my #4 solution?
