ZeeVee ZvSync High-Definition Digital Cable Tuner

I'm sorry, this tuner cannot map channels.

The decision to not include a built in ir receiver is intended to decrease the possibility of bad ir reception. Per the manufacturer, "The receiver/decoder is supplied with an external IR receiver. This is in the form of a cable with an IR receiver at the end.The pigtail MUST be installed for the ZvSync to receive commands from the remote control device and is required for proper operation. By separating the Infrared receiver from the base unit, the main body of the ZvSync receiver/decoder can be installed in an unobtrusive location with only the IR sensor showing. The 3.5mm plug on the Infrared pigtail must be plugged in to the front "IR" port on the ZvSync main unit for proper operation."

This is a very nice digital QAM tuner that works well in a facility that does not have encrypted (aka scrambled ) channels. It will not decode scrambled channels, that are delivered by the cable providers. If you need a cable box from Comcast or Charter or Time Warner, in order to decode your channels on your TVs, you'll need one of their boxes for your projector. OTOH, if you can direct tune your TVs, your channels are in the clear and the ZvSync will work.

At this time, most cable companies are scrambling the signals, and this will not work. If your cable company allows you to tune the TV signal without any kind of cable box, and modern TVs can tune in the channels, then yes, this should work fine.

It supports up to 1080i resolution which is HD.

COnflicting answers to this question, previous answer say it will demondulate ATSC

If Verizon allows you to use a QAM tuner for basic programming, then you can use this tuner. However, your TV probably has a QAM tuner already. Like most providers, Verizon scrambles their programming and will require one of their boxes.

I don't think so. It is a qam tuner so it only tunes digital cable type signals. VCR's only use NTSC analog frequency modulation on Channel 3.
