I’ve just purchased a DMR-EZ17. It is equipped with analog and digital tuners capable of tuning up to channel 135 in either analog or digital formats.
The Specifications section of the Operating Instructions for the new Panasonics, DMR-EZ17, DMR-EZ27, DMR-EZ37, DMR-EZ47, DMR-EZ475, and their variants, all show the same 135 channel range for analog and digital tuning.
My DMR-EZ17 is connected directly to our Comcast Cable coax (without a converter box). The DMR-EZ17 relocates most of the digital and/or HD versions of local channels down next to their companion channels. Of course HD channels are viewed and recorded in “standard definition” with the DMR-EZ17.
Most of the Comcast digital channels are located well beyond the tuning capabilities of the DMR-EZ17. TCM, my favorite channel, is found on our local Comcast service at channel 501 among many other digital premium channels (the Encore/Starz, HBO, Showtime, Cinemax, Movie Channel, IFC, FMC, Sundance, etc. groups) in the 500 channel range. HD channels are located in the 700 channel range. Music channels are located in the 900 channel range. I receive the digital channels with a Comcast digital cable box in another room where I have two Panasonics (a DMR-ES35V and a DMR-ES30V) as slaves to that cable box.
