Re: Spectrum Quad Tuner DVR revealed 1. 3 + 1 live or 4 with live being recorded as well.
2. maybe 500GB or more HDD + likely E-sata but turned off like other comcast boxes.
But with out MRV 4 tuners is a lot hardware locked to 1 TV unless it can do U-verse like split screens with up to 4 on 1 tv at the same time.
The Direct New MRV box with 5 tuners will have E-sata with plans to make it add space right on Directv E-sata overrides to build in HDD and maybe being able to stack boxes for more tuners right now you can use more then 1 directv DRV in MRV.
Dish has new 3 tuner real HD MRV boxes that can stack to add more tuners to the pool.
But right now cable is stuck with 2 tuner MRV boxes.
So I think comcast needs to have this work with 4 tuners in MRV.
