I've been having this issue for a while. It was only happening when trying to record the E! news for my wife. Randomly, a few episodes of E! news wouldn't record, or the recording would stop half way through it. I would get the following message "Restrictions that were set by the broadcaster or originator of the content prohibited the show from being recorded."
I didn't care because it was only happening to that show. But now, it has canceled the recording of my Formula 1 race. I am pissed. Again, it's random. It canceled half of the qualifying race 2 wks ago, and canceled the actual race this week. The funny thing is that is recorded a replay of the qualifying race without trouble later in the day.
I tried searching online and couldn't find a fix. The closest discussion to my trouble was found on the greenbutton forum "AVSforum is preventing me from posting the URL, search for greenbutton Copying Prohibited (works again!) " but when I tried installing KB956147 , it told me the update doesn't apply for my set up.
My set up,
Vista home premium 32bit
VMC with TV pack fiji package installed
Hauppauge 2250 with one tuner recording digital qam and the other analog cable.
