Matthew, I couldn't tell, but is that with a sat. input or a cable input? I've never had a lag that long on cable, and actually, I have my Tivo controlling a sat. box via serial and it still doesn't take that long.

When it comes down to it, I say it's subjective. I tried both systems out, I loved the Tivo. Go to Best Buy and try them both out.

Yes, Tivo has video extraction...sort of. It gets better all the time, though. I'm still waiting for the day when I can take it off the unit, easily edit out the commercials, and burn it to DVD, all using one program (maybe not the burning part). Are you able to edit out the ads from Replay after you've extracted them?
