Advertisements Yep I know. However from what I read the 4 tuner Recast can only record 2 channels at once or something like that. Or it can record 4 channels, but only stream 2 shows or something? And if 2 people are streaming something then it can only record 2 channels? I guess you'll let me know how it works exactly. I don't have one. But I read there was there was a bit of a catch to "4 tuners" that I don't think is present on a Tivo system because watching a recording on a Tivo system doesn't have anything to do with the number of tuners you have iirc. And again, if you really want a new 4 tuner Tivo system then 2 2 tuner Tivos doesn't cost much more than 1 4 tuner Tivo and 1 Mini. You can create your own 4 tuner system on Tivo in other words. But yes it would be quite a bit more than a REcast system.
