Comcast XFINITY TV → Re: When will Comcast HD box record more than 2 shows at 1 time?

then every box you have would be a DVR and would circumvent ads being run by stations....wanna change the fee associated with every box in your house?

It's not a full DVR. You can't record, only buffer. You can rewind back, but you really can't "skip" a commercial without seeing it first anyways unless you physically leave the room.

they need a system to compete with the hopper and genie.

Actually, in his LRC article about the IP-only XI3 box for the X1 platform (»www.lightreading.com/doc ··· lr_cable), Jeff Baumgartner speculated about one possible use for its SD card slot:

And what's with that SD Card slot? The XI3 doesn't have an internal hard drive, so the slot could be used for memory expansion. But it's also plausible that Comcast could use an SD Card as a local, mini-DVR that could buffer a small amount of live TV programming for trick-play functions (pause, fast-forward, rewind, etc.). Advanced Digital Broadcast (ADB) toyed with the notion of using an SD Card as a "lite" DVR for a tru2way "set-back" box it showed off in 2010. (See Tru2way 'Phantom' Box Is a DVR Lightweight: »www.lightreading.com/doc ··· lr_cable)

Looks like that use is not just speculation, given this statement in a press release from Entropic (»www.globenewswire.com/ne ··· ice.html) on the use of their TSC188 chip in Humax's XI3 box:

The compact Humax device includes recording functionality. The DVR feature works in conjunction with the multi-tuner hybrid gateway server and the on-board SD Card lets the IP set-top-box stream and play back programming using the MoCA specification.

directv and some other systems does not change a per box drv fee like comcast.

the X1 has more tuners but only 3 are tuned on and it does not work in multi room.
