I've been following these threads for a while, but I only just got a 3576 last week, ( pack date: 24 June 2008, DTS-V: 0x93. ). I was going to wait a bit longer before posting about the "cannot copy to disk" flag, but I'm seeing a pattern too clear to ignore. I'm in Toronto Canada and I get my signal ( digital and analog ) OTA - Canadian channels from the Toronto area and American channels from Buffalo NY. Thus far, I have recorded about twenty digital shows in total, and I always get the flag on every American broadcast recording, ( from the Buffalo affiliates of CBS, ABC, the CW, FOX, and MYTV - formerly the WB ). The only exception ( no flags ) is PBS. I have never gotten any flags from a Canadian broadcast, even when the show being broadcast is an American network show, like House or Bones.
This would seem to support the theory that these flags are appearing as a result of advancements in anti-copy protection either at the broadcasting station or in the recorder or both. The pattern is just too stable and consistent, (in my particular case anyway ), to be a malfunction on my machine or the result of some kind of interference.
I suppose that the other possibility is the commercials. Most commercials on Canadian channels are made for the Canadian market. There are some that seem to be running identical versions on both sides of the border, but I don't know whether they might be altered for Canadian broadcast in a way viewers would not notice, ( closed captioned in French or something... ), and there are next to no commercials on PBS.
I don't have a problem with this because I'm just timeshifting. A pvr with added bonus upconverting dvd player suits me just fine. I know that my overall experience with this is limited and I should wait much longer before making definitive statements. But I thought the pattern was so striking that I should report it to those of you trying to figure out what's going on.
