I've built an HTPC and have Silicon Dust tuners on my network, but I abandoned the idea of replacing my Tivos because I thought the amount of tinkering/maintenance would be too high to use them as anything more than toys. It's cool to have, but it's certainly not mainstream. Heck, most just settle for whatever the generic cable company DVR is. I have two Elites and two Premieres, so I have more TiVo tuners than I really need, but I would still like to see cooperative scheduling (I live in the Mountain Time Zone, so I have to start every network program two minutes early (or maybe it's just a Denver local issue). That would be the single biggest addition to base function in a long time. As others have said, with MRS and the Stream, it no longer matters where a recording resides, but it can still take a lot of work setting up Season Passes and scheduling to get those recordings in the first place.
