I was thinking about getting Tivo for OTA but I'm not sure anymore.
If it is OTA you need, then go with the upcoming 722K or 922 Duo. The only thing I can say that is "value added" or superior about the Tivo (Series 3) is that the broadband selections are much better. I do love getting The Onion downloaded along with CNET and some others. I did download 2 things from Amazon.com. Other than that, the Tivo is OK, but Dish DVR's (522 to 922) are superior in just about every other way. I find Tivo's lack of PIP quite annoying, and when you toggle between 2 channels, the buffer dumps to live, and that is annoying as well. Also, the Tivo Menu is more cumbersome than Dish's Menu. With Dish you can press a corresponding number and to through the menus much faster. Also, no Picture when you enter any of the Tivo menus, also annoying. Those are just a few things that I don't like about the Tivo.
However, I am not bashing it. Tivo is still pretty good and is most likely a much superior alternative to cable branded and OTA DVR's. In fact, Echostars MyPal DVR is a stripped down version of the best Dish DVR's, and Tivo seems superior when compared to that unit. Of Course, the lack of monthly fee is a great incentive to put up with what my be an inferior Pal DVR.
Also the Tivo addition of the external HDD is VERY restrictive. ONLY one model of the WD My DVR Extender certified by Tivo will work, and it must be
connected and powered to the Tivo
AT ALL TIMES. It records directly to the HDD and all recordings are integrated, giving the experience of 1 HDD. However, if you disconnect the external HDD, you will lose all your recordings as Tivo will reformat it. This is how it designed. So, in other words, no multiple external HDD support as with Dish. There is a process you must initiate using the software (via the menus) that will allow you to prepare the unit for a momentary loss of power or the external HDD should you need to physically move your
unit to another room. And no, the external HDD cannot be disconnected, then re-connected to another Tivo unit. In other words, the external HDD is FOREVER MARRIED to that one Tivo unit, excepting for disconnecting the HDD, then reconnecting it to a different Tivo unit that will reformat it, lose your recordings, but now you have a fresh HDD for that other unit. I hope that wasn't complicated.
Again, overall, Tivo Series 3 (HD and HD XL have the same menus and functionality) compared to 722 has the 722 the winner, in my book
