Ah, welcome to 2006, the year when DVRs went completely to hell. What are our choices?
* HR10? Dead-end product that seems increasingly unstable with each release
* HR20? Less stable than the HR10 for many after 13 software releases in 3 months
* SciAm/Moto? Crappy UI, limited HD space, etc.
* Series 3? Seems good, but costs a bundle and doesn't have some of the famous Tivo features (MRV, TTG). Oh, and cable companies will make the CC 1.0 slots obsolete in a year or so.
Are there any choices that actually feel like an upgrade anymore? I can't see any
The HR10 isn't perfect, but until very, very recently, it was a reliable & functional HD DVR. Now my HR10 reboots at least once/week, and I know from reading here it's unlikely that it's a hard drive issue. If you call DirecTV they'll give you the runaround, or try to make you "upgrade" to the HR20. Or I switch to cable, with any of the options (build my own box, Series 3, Motorola box) I get at best a sideways trade in features and a big increase in cost.
It sounds like out of the frying pan and into the fire, no matter what you do.
