Sorry to be the newbie (haven't been one since '99 here...), but I have a few basic questions regarding DirecTivo. I spent most of my afternoon at dbstalk.com and tivocommunity.com but didn't find my answers. #1. I have a single LNB Pegasus setup. Can I simply buy a Dual LNB and install it myself? I'm also planning on an upgrade to HDTV soon, would it make more sense to buy a Triple LNB and install it at this time? I see that most DirecTivo units are dual tuner, will I be OK just skipping the second tuner if I choose not to upgrade to the Dual LNB. #2. I'm planning on buying a small (40GB) unit and upgrading it via a "regular" HD. Is there a recommended unit (of the 40 GB models) or are they all the same? #3. I see a mention every so often about a "lifetime subscription". I would assume then there is a monthly subscription option as well. Is this in addition to the $4.99/month charged by DirecTV? Thanks!
