And DeadFire, have you come to any decisions?
No, I don't think I have. When I started this thread I was obviously leaning toward the ReplayTV.
Basically, I don't think I want to do any hacking. I'd rather have something that does what I want out of the box. The ethernet features of the ReplayTV are very appealing. Especially when you consider that I have a friend looking to do something similar, who watches many of the same programs I do. Thus, if I get a ReplayTV, he probably will, too, in order for us to be able to share shows or use it to suggest programs to each other simply by sending them. Also, since not all networks follow the same clock, I like using my VCR to record extra minutes before and after a program.
But, it seems that people who like TiVo like it for how it handles the basic common tasks (i.e. conflict resolution, searches, "suggested" programs, space management). And more of the people who have seen both units seem to favor the TiVo for the same reasons. I get the impression that the ReplayTV doesn't cut it in that case.
I think I've come to the point where I'd rather stick with the basics. When this all began, I simply wanted to replace my VCR in order to have more recording time and better quality. Either unit will serve this purpose just fine. The extra features have basically hindered my decision.
So I'm still undecided. But I think for now it's going to have to go on the back burner. I've got Christmas shopping to do, and probably won't be able to treat myself anytime soon.
