You can also use Alexa with Fire TV Recast. The smart assistant can search for shows, browse the recordings you have on the DVR, change TV channels, control payback and manage and schedule recordings. There are no monthly fees, but only one Fire TV Recast can be registered per Amazon account.

The device is made for people who've cut the cord, but still want to get network TV shows or sports broadcasts to go along with streaming services like Amazon Prime and Netflix. Others like Tablo and Simple.tv have offered "headless" OTA DVRs before, but attaching Amazon's name and Alexa technology to the device -- and boosting its promotion in search results -- could increase its appeal.

You can pre-order today, with prices starting at $230 for two tuners (recording two shows at once) and 500 GB storage space for up to 75 hours of HD programming. A Fire TV Recast with four tuners (that can record four shows at once) and 1 TB is available for 150 hours of HD programming as well for $280, with deliveries expected to begin on November 14th.
