Has anyone run across TV shows that are copy protected? I haven't encountered this myself, but I've heard that cable channels like Discovery, Travel and Science, that make a lot of money selling DVDs, tend to copy protect shows. (I don't even get the latter two channels and don't often record anything off Discovery.) Are certain cable/satellite providers more prone to this sort of thing, or does that matter? I've heard that this happens with DirecTV. I used Comcast and haven't had a problem. Thinking of switching to DirecTV or Dish Network, which is why I'm wondering if there's any difference.
