Here’s a message you don’t want to see on your Media Center machine:
This occurs when you try to play back a copy-protected file – in this case, a movie recorded from HBO Signature – on a computer other than the one it was recorded on. Media Center Extenders include code that bypasses this restriction so that you can view recorded shows elsewhere on your network, as long as they’re playing back on the main Media Center box where they were originally recorded.
The trouble is, I got this message when I tried to play back a movie on the Media Center machine where it was originally recorded. And now I see that the same problem is affecting another movie recorded the same day, from the Starz channel. What went wrong? I’m not sure. Did I copy this particular movie file to a different partition?
I’ll do some more tests and see if I can figure out where the problem lies. Meanwhile, I won’t be watching Three Days of the Condor or Lenny anytime soon.
