key exchange for copy protection

Can’t get Margi DVD player to work on my Compaq laptop.

Have compaq armada 7800, with 366 cpu, 228 memory, installed a Margi DVD video accelerator card.


Using DVD to go player that works with the margi card.

When I try to play DVD, message Key exchange for DVD copy protection failed. Playback is stopped."

Any ideas on how to get past this problem.

Power DVD works, but video is slow and sound a bit choppy.

thanks
