zonker asks: "We are getting hooked up with Dish Network Satellite TV this weekend and opted to go with one of their PVR (personal video recorder) plans. I started wondering if anyone has done any technical reviews or comparisons of the video quality (not just features) of the various digital video recorders out there (TiVo, DishPVR, ReplayTV, etc.). I am curious mostly about recorded video quality compared to the source video. All of them make claims to have various recording 'speeds' like VCR's. VCR's analog output is predictable (fuzzy recording with bits of static here and there, worse when signal quality is bad). However digital recorders have varying levels of pixelization. I was curious which ones fared the best and if anyone has comments on either systems?"
