Hi TiVo Friends, Sorry if this has been asked before, but I did a search and didn't find an answer to this question. To make a long story short we have finally upgrade to a Premiere XL from a single tuner S2. We're also moving to a new location and will be using FiOS TV. Currently have Optimum and one STB for the S2. I need to order FiOS TV and I know I need a CableCard for the Premier XL, but was wondering if I should also get an HD STB to go alongside the Premier XL? The reason I ask this is that with our Series 2 unit changing channels can be incredibly slow. I don't want to spend the money on an extra HD STB if I don't need it, but have never seen a Premiere XL in use nor have I seen FiOS TV before so I don't know what I'll be missing w/o the HD STB, but want to order it if I don't need it. Thanks in advance for your help.
