I have a Roamio basic for a main unit, as I need to work with an antenna input. I want similar features and access on my bedroom television. What's the pros and cons of a mini versus a premiere (Series 4)? I'm guessing the areas of concern would be stream versus share, network traffic, cost (to a minor degree), quality of viewing, and speed of viewing. I'm sort of a TiVo newbie, but an electronics engineer, so I'll share my first thoughts.
Stream versus Sharing
I'm guessing that I can stream shows with a mini, but with a premiere I have to share/transfer the show to watch it.
Based on my stream versus sharing, network traffic will only occur during transfers with a premiere, but streaming will eat some bandwidth while viewing. I see topics about "constant network chatter", but I've not seen a real network analyzer used to gage severity. I have this ability given borrowing equipment. I have WIRED gigabit setup, so maybe I shouldn't be concerned? I haven't even verified that the Roamio has gigabit wired port. Premiere most likely doesn't, but haven't verified that either. I live in an area of all 5 acre plots, so not concerned about wireless network traffic. Atop, I also have high-power, Wireless-N, industrial wireless access points (Ubiquiti).
Mini is $88 (Amazon), plus $150 lifetime service = $238
Premiere is ~$350 used with lifetime service, so ~$112 more than a mini
Quality of Viewing
Expect no difference in viewing quality given fully wired connections.
Speed of Viewing
Given that I expect to transfer a show with a premiere, I would guess a mini could be watching instantly, but I'd have to wait for a period of time (~ 5 minutes with wired gigabit?) before starting to watch a show with a premiere. I don't think I have to wait for the whole show to transfer, right?
Sorry for the length, but wanted to help clarify my thoughts. As an engineer, I'm always weighing pros / cons.
