And about your second point, the DTivo's with 40GB get 35 hours record time at low quality whereas the 40GB Replays get 40hrs. I know because I have owned both and reviewed the topic extensively (Phillips DVR 7000 and Replay 5040). Show me where you got that information from.
I am a replay owner and fan, and I have to let you know that you are wrong.
While ReplayTVs are said to have better picture quality than Stand Along Tivo's, DirecTiVo's have better quality than both. That is due to the fact that there is no need to encode an analog signal to mpeg. It already arrives in mpeg format.
While you get 40 hours on a Replay 5040, that is only at its lowest quality setting. At high quality you would only get 13hours or so. DirecTiVo's give you 35 hours at their only quality setting, which as I said above is superior to Replays.
If you have DirecTV, the TiVo combo unit is probably the best unit. If you have cable, then you should figure out what features you like best.
In regards to software, the general consensus is that while TiVo has superior recording features, Replay has superior playback features. Plus Replay has the networking stuff built-in.
