Yes, like all Tivo owners I get annoying with this stuff. But, the great thing about the new two way video transfers is that it lets everyone hook up a huge external drive and essentially remove any capacity limits from your Tivo. No more need to hack the Tivo box to "put in" a bigger drive if so desired.
And, yes, no one should ever watch TV because it's all bad.
And, yes, for more money and a lot of time I could build a noisy unsightly box which would be four million times better.
And, yes, Replay could do all this back in like 1648.
