What would happen if I did?
What I'm doing is: I am not willing to spend $1000 on a HD TiVo with directv. So, I planned on leaving my standard DVR 40 receiver and directv's HD receiver. So, when I want to watch HD programming, I should turn off my TiVo receiver?
Would it be better to split the digital or optical?
Can I buy a splitter like this from a retail store?
