As recently discussed
here, Vista Media Center users in the U.S. got a rude awakening a few weeks ago when they were unable to record some of the favourite programs on NBC. What really got them scratching their heads though was that unlike the normal improperly flagged content cable customers have grown all to accustomed to, this one affected over-the-air (OTA) users as well.
This was odd because the broadcast flag had been struck down by the FCC which should have been the end of it. The problem was actually a cable content protection scheme called CGMS-A, and when NBC inadvertently flagged some OTA content copy-never with it, users were left in the dark. While there's no way to tell if NBC has learned its lesson, the good news is that Microsoft has, and the
Windows update KB950126 will change that behavior.
Now inadvertently flagged content coming into VMC via OTA or analog cable will be recorded regardless of how it is flagged. Unfortunately the same can't be said for those with CableCARD tuners or connected to a STB via S-Video, you're still out of luck.
