As mentioned, it has, until recently, been working fine for me. I have been recording HD movies, with 5.1 surround sound, from the HD cable channels. I then process the resultant files with Handbrake (Apple TV 3 settings) and keep the MV4s in my iTunes library, ready for playback through one of my Apple TVs. I can still do it if I manually change the channel before the scheduled recording begins. FireRecord, while minimal in features, still works well for my use. I had retired a PPC PowerMac (Leopard), but now it is my network media server.
Still looking for the resolution to the issue. It could be the 6200, but I had it completely reset this afternoon. That didn't fix the problem.
