    Maybe an aftermarket Ebay one is $10 to $20! OEM AC adapters for laptops and other powerful devices typically run in the $40 to $75 range...

    Even Radio Shack brand, which is likely not enough wattage, is $35 to $40. http://www.radioshack.com/product/i...nSession=1&filterName=Category#stuff-you-want

    The Mini uses a 12v 1a brick. Assuming the TiVo needs a bit more power lets assume a 1.5-2a supply. There is one of those on Amazon, with Prime shipping, for $6. But even if it costs $40 like the RadioShack one it's still cheaper then the $100+shipping it costs to buy a S3 power supply from Weaknees.

    It wouldn't surprise me one bit if TiVo made the connector off spec a bit so you'd have to buy the replacement brick from them. :rolleyes::p

    Does TiVo have the money and clout for custom stuff? Apple does stuff like that, but they can afford it.

    I hope not because even now I don't see a replacement brick for the Mini listed on their site.

    Thanks. I was referring to speed difference between Roamio and Mini though... Not between Roamio and Premiere.

    I wish someone would look at theirs and post the specs so we would know :eek:

    Ah. We don't really know. There aren't any detailed published specs for the chip in the Mini.

    Another thread had a photo of the inside of the base Roamio unit. Unlike the older units, or the new Plus and Pro units, it appears there is no external fan, but there appears to be a fan between the area where the disk drive is located, and the rest of the machine. How does air get in and out of the unit? Is this likely to have a negative impact on the lifespan of the basic Roamio?

    If you look at that pic, you will see on both sides of the unit has vents, so the fan pulls air in by the hard drive, pulls it over and past the drive to cool it, and then blows out the back of the fan across the motherboard to the vents on the other side. right to left in the photo.

    Another thread mentioned that while the TiVo web site shows all three new Roamio boxes having 1GB Ethernet, the base unit supposedly only has 10/100 MB/sec Ethernet. With a base unit on order, this is a little frustrating. How efficient is the TiVo when it comes to transferring data? How much longer will it take to move an HD episode of an hour long show from the base Roamer to my Mac using KMTTG vs doing the same transfer with the Plus or Pro? (I can do the math -- I'm really asking if the theoretical network throughput is the limiting factor, or if something else in the path diminishes the value of the 1GB interface when it comes to throughput).

    Thanks for the detailed info. I think that should do it. Since heat rises, I'm thinking I should shuffle the three components in my entertainment unit to have the heat generating A/V receiver on the top shelf, and the cooler TiVo and Blu-Ray players below it. Right now the TiVoHD is on the top of the three shelves. I do, at least, keep the doors open on that unit at all times, but it still feels warm in there.

    Yeah, and no RMA hassle with TiVo (buh, bye, recordings) handing you back a refurb with likely the same vendor PS, nor dealing with 3rd party (weeknees) having to ship back and forth. I would certainly expect Weeknees and others to sell the replacement external PS, for those who want to get from them as opposed to a compatible brick from a less expensive maker/seller.

    Oh, yeah. Very good point as others are doing the same. However, it may be a case of insuring that the proper brick is connected and avoid situation where folks who aren't as knowledgeable getting an off spec brick. If TiVo does have odd connector, fine. Just price the replacement reasonably. I really don't have a problem laying out as much as $30 plus (a big mark-up, I know) to get my TiVo back up and running and saving any shipping hassle and cost losing recordings on an exchange with TiVo (we're talking about the masses here, not our embrace of software to move recordings, etc.) or breaking the thing open as with previous models. Of course, gang, this is ONLY the Roamio we're talking about, not the Plus or Pro.

    I would really love people to upload videos to YouTube showing us real-life UI and speed of commands and screen changes, etc in real time. I'll keep searching there each day. I feel nearly 100% I will get the Roamio for my OTA needs, but I will wait just a bit to hear of any bugs, etc. to see if I should wait longer for fixes, or, really hoping for, the Roamio performs pretty well upon release, then I'm getting one--after selling my S4's.

    Fyi_ hot air rises, while heat conducts. The fan is sucking out the hot air that the heatsinc pulls from the chips.

    It doesn't show a ton of it, but they do show the UI in action.

    The power brick is a 12V 2 amp unit using a standard barrel connector with positive voltage on the center electrode. These will be cheap to replace if they fail.

    It also means the Roamio base unit uses less power than a Premiere as the power supply is only rated at 24W max which is less than the idle power of the Premiere.

    Minor point but the brick isn't 100% efficient so it will use more than 24W max. On the other hand, the Roamio probably doesn't draw 2A on average.
