Tivo Premiere XL4 Review http://www.engadget.com/2012/05/10/tivo-premiere-xl4-review/ I have to wonder, why didn't Tivo port this current experience to DirecTV? The XL4 has 4 tuners, but if they ported it to the HR34 it could have 5 tuners. That grid guide and mini guide are nicer in the Premiere than DirecTV's HDGUI. (More information on screen). Love the 8 channel guide and 3 channel mini-guide. Its a shame because if this was it along with Tivo's Moca and eventual roadmap to multi-room dvr, it could of made a real hit on DirecTV via the HR34 and DECA.
