I have a TiVo Series 2 DT Digital Video Recorder. TiVo Model # is TCD649090. Got it from one of my kids who discontinued their DirecTv service. On my Current D* system I have: 1 HR20-700 DVR (Working great) 4 D12-100 (all working great) Whole Home Service (though no second HD receiver yet -- still looking). HD Service SWM LNB - 3 head So ... can anyone tell me what the TiVo listed above will do for me if I get it reactivated? How would I hook it up? Is this TiVo unit HD or SD? and anything else I should know? (maybe a pointer to somewhere on the net where I can get such questions answered?) Thanks in Advance!
