In TiVo hacking, only a "moron" would keep their box connected to the phone line in the first place.

On a Series 1 DTivo, yes, you can run a Sony image (at least of 3.1.x) on a Philips box (that means an actual Philips or Hughes). These units are pretty much all the same really.

P.S. The TiVo forums (linked above) are mostly full of hot air. So I try to avoid them.
