There are so many threads on this already, but here I go:

Tivo. Because I have it and I like it

If you have so little time and just want something to watch shows with no trouble and enjoy doing it, get Tivo.

And adding ethernet support on a Series 2 box is so easy it's ridiculous. You buy nearly any USB-to-Ethernet adapter, plug it in, change the dial-out prefix in-menu, and you're set. Much better than opening your box and adding an ethernet card like I and so many others had to.

Anyway, yeah, Tivo.
