There is somewhat of a similar thread on here, but it goes back to '07, so I'll move on. THe setup is - I have Comcast cable going into a TiVO HD (with an M-Card). The signal I get (according to the TiVO Cable Signal Strength thingy) is 80% or better on most channels. I wanted to split the signal, with one going to the TiVO and the other to a digital (non-HD) box in order to get On Demand. When I did that, the signal deteriorated on the TiVO to 50-60% and lower on most channels, I got pixielization on several TiVO channels, and on the digital box, several channels would not come in at all (again, no big deal there because I was only going to use it for OD). My question is - would a signal amp/booster help? I've used an amp years ago when it was all analog, but I'm wondering if this would help me in this situation. OR is there an amplified splitter that would work?
