I plan on trying to use a premier just for SD shows. Can I skip the hassle of dealing with TWC trying to screw me again (as I went through it with my HD tivo a couple years ago)? From what I've seen on here, it looks like I will still be able to tune any SD channels without the cable card, correct? Will I still have the dual tuner aspect even if they're both in SD? I guess my question is what what I be missing other than HD channels and channels that are only on SDT at this point? I'm on the fence about just buying another series 2, or trying out a premier... Thanks!
