Newbie here need advice.... I want to be able to switch channel while recording from another channel. This is what I have now. Digital Cable from Wall --> Cable box --> Tivo --> TV. From what I read, I think I can split the cable after the cable box : one plugs into Tivo, the other directly onto the TV. The thing is, I also plan to upgrade to S Video connecting between cable box and Tivo and TV. Should I use a S Video splitter? Or should I forget about S Video and just split the regular cable? I hope my question make sense. Thanks.
