Try http://www.nwlink.com/~zachd/pss/pss.html#screencap but the second answer is that http://www.mpegla.com/ is that MPEG stream licenses are per output and some drivers just drop the video.
PowerDVD's web site notes the copy protection issue.
On Cyberlink's website for PowerDVD which explains why I cannot see my DVD movies on my TV but I can on my monitor:
"The main reason is because the DVD Forum asked all DVD player developers (hardware and software) to protect analog output (TV-OUT) by MacroVision. Therefore, the problem may caused by one of two reasons:
1.When the MacroVision chipset located in your VGA card detects the electric equipment which is connected when the TV power is on, it will interfere TV-OUT function.
Our suggestion: Please turn the electric equipment power off which is connected to your TV.
2.There are many display cards in the market with a built-in TV-OUT function. However, there are some VGA cards that are not approved by MacroVision. Therefore, a DVD software decoder, like Power DVD, is forced to shut down the TV-OUT function to prevent any illegal
Our suggestion: Please find a VGA card approved by MacroVision. Then you can watch DVD via the TV-OUT function.
#2 applies to me since my card is apparently not approved by Macrovision.
Is there a DVD player out there that will NOT shut down the TV-OUT function? I did receive a message from the support people for my video card that supplied the following information (I haven't tried it yet):
First, plug-in your computer to your TV using whatever you usually use, in my case I use A/V plugs from my video card (with the latest driver). Once your computer has booted up and you can see windows on your TV. If you try running either PowerDVD or Windvd it won't work.
For me PowerDVD gives an error saying it can't disable the TV-Out port and in WinDVD, all that I get is audio and a Windvd logo showing up.
So before you run either program, set your computer to switch back to the VGA mode (in my case click on the Asus Control panel in the tray, click on Display and in the top right-hand corner is a dropdown menu
with TV or VGA in it). Once the VGA mode is active your TV should go blank, but after 10 seconds or if you press the Escape button it should switch back to the TV mode. Now try and run PowerDVD or WinDVD and for some magical reason it will work and you will be able to view your DVD's on TV instead of the monitor."
