NBC responded to complaints from Vista Media Center users who said they were unable to record “American Gladiators” and “Medium” on May 12, CNET reports. A NBC spokeswoman told CNET News.com that the network had “made an inadvertent mistake,” but declined to explain how the mistake had happened, the Web site says. Broadcast flags are sometimes used to prevent users from recording shows at the network’s request, the Web site notes.
