I have two DVRs and a Motorola DCT7000 Digital Set Top Adapter in my house. I can use Verizon's web site as well as the on-screen menus to find the channel lineups for the DVRs, but the channels on the Digital Set Top Adapter (little grey box) do not match the published channels. Is there an alternate lineup somewhere? (For example, PBS is on channel 22 and Comedy Central is on channel 1644!)
The DCT700 should have all the SD channels in the the same place as the full featured boxes, it just doesn't support any HD, VOD, PPV, or have a guide.
For instance, Comedy Central should be on channel 190 (SD version). The 1644 channel you referenced is most likel.y a duplicate (mapping olnly - not a duplicate of the channel) for the Spanish language package (or some other foreign language package even though it may be in English).
Good call. 190 is CC standard def on my normal DVR and is the same thing as 1644 on the Motorola mini-box. Kind of bizarre, but I'm really glad you knew. Thanks!
