I wish you both the best of luck with your systems. We've had it installed for about a week now, and it's giving us a lot of trouble. The program guide information took forever to load. After 3 days, we were still missing about 1/4 of it, so we called and they "sent a signal" to each box which cleared it all out. About a day later it was all loaded.
Once we thought it was all finally setup, my wife created about 50 series recordings and then checked the "future recordings" list to ensure there were no conflicts and that everything would record for the rest of the week (red dots vs. red not signs). Everything looked good. We didn't really touch it again for 3 days, as we had lots of shows on our old TiVo to watch before watching anything the Insight box was recording. But when we did look at it again (tonight), there were about 9 shows that simply weren't there. These were shows that 3 days ago it claimed it would record. There is no history that we can find to tell us why it didn't record them either.
To top it off, we couldn't play anything or watch live TV from one of the boxes either. I couldn't find any way to fix it other than power failing it (pulling the plug). Once it booted back up (which is surprisingly fast, especially compared to TiVos), it could show live TV and play the recordings again, but the program info was gone. We started to freak out, worrying it would take another 3 days to load and we'd miss even more programs, but about an hour later it showed up.
Maybe it's just going to take some getting used to, and probably a lot more babysitting than we're used to with TiVo. The only reason we switched is because of the stupid digital rights crap that prevents programs from being transfered between TiVos. Insight gets around it by keeping a single copy on NAS and streaming it to multiple boxes. If TiVo ever supports that, we'd switch back in a heartbeat.
