Ask HN: What DVR do you use?

I'm sick of the crappy generic DVR my cable provider offers me. It locks up constantly and the data, like scheduled recordings, eventually gets corrupted. This is the 3rd box I've tried so it's clearly a problem with the underlying software & hardware.

I recently ordered a Tivo premiere but the software is awful. The overlay menus are hard to read and at times prevent me from watching TV until I complete an action.

Now I'm left with the option of staying with the poorly built generic DVR, Moxi or DIY with Windows 7 Media. Moxi seems like the most promising option.

What does the HN community use for a DVR and are you happy with it?
