I've had my network on mine quit exactly once but I was able to get it going again when I fired up the other PC here that was working, which then found the Prime and for whatever reason it made my PC here happy too as before I couldn't get it to rejoin the network at all after trying a bunch of stuff. It could have been a of of issues for WB, from his network card , something about the way his OS and media center are working, maybe his units were bad, who knows.
Luckily I haven't totally missed any recordings yet and mine continues to just work so I'd say most users are happy, just like it seems the Ceton users are very happy with their units, especially the PCI versions I guess.
It would be nice to have a totally standalone unit so you don't have to have any computers tied to it and running but now that I have it and my sleep mode works it seems a small price to pay for all the cool stuff it does.
Sounds like that new Ceton Q 6 tuner thing is possibly fully standalone but I can't justify the money it will cost, but for those that can it sounds like a great unit.
