Satellite companies are also incorporating similar anti-recording schemes in their bradcasts. Many programs coming out of the box are using a copy once flag which basically essentially works the same as the CGMS copy never flag coming out of dvds. The copy once signal will give a message like, this program not recordable in +VR mode. This requires a dvd ram disc or a videotape, but then you cannot go from tape to dvd in that same machine that has that dubbing function.

Macrovision introduced ACP (Analog Copy Protection) to prevent copying VHS. The VHS Recorder is looking for something off the visible bandwith (in-between frames ... same place that closed captioning comes from). It won't copy if it finds it.

So they built it into the DVD format (so that DVD's could not be copied onto VHS).

Hi, I had this issue a year ago, my PC worked fine for months, It payed DVDs and Stuff, but this problem suddenly appeared. I tried a lot of players but no VLC, so the only solution I found was restarting Vista from the Install CD, I was really annoying but it worked.

and now I have this problem again, but its more serious than I thought before, you know this problem prevents you from playing any HDCP protected material, but affected not only my PC, it completely messed up with my monitor which is an HDCP compliant monitor but now it doesn't work with HDCP required hardware.
I had my PS3 connected via HDMI and worked great, but science I had this problem with my PC, my monitor, a complete different and independent piece of hardware, went crazy to, it doesn't allow me to display any kind of Copy Protected material coming from any source (PS3, Blu Ray players, HDDVD players, HDMI Upscalers, nothing, all I get from them its a blank black screen.

The only thing I can do is restart my PC again and hope this solve the issue with my monitor to.

Aside from it's ghetto UI, VLC seems to play anything and runs well on any OS. It is funny though how much trouble people have gone through to enforce the copy protection that libdvdcss easily circumvents.
