A tuner selects a channel from the antenna or cable. TV's have a built-in tuner for off-air broadcasts or you can connect the output of the cable box (a tuner plus descrambler) directly to the TV. In the olden days, people would record TV shows off the air and the VCR would have a tuner built in that would tune to a particular channel at a given time to record a show. Modern VCRs lack a tuner because a TV show is seldom recorded on a VCR which lacks the capability to record in HD or even DVD quality.

That is a good question. If u r using your camcorder as a DVR and the manufacture says it can be done, then yes. Using the proper cables and if there is an "In" jack on your camcorder then it can be done. Best bet is to check your camcorder's manufacture site for specifications.

It does come with a remote

Yest you can. That was how I was sure that it had recorded. You have to make sure that you finalize the DVD or it will not play at all.

Yes you can. Just change the input of your TV

I have been able to record any movie on cable, including PPV, by setting the TV Input to normal HDMI and clicking "Rec" on the remote. I cannot record it if I try to use the timer function, so I have to be there when the movie starts and stops if I just want the movie without other stuff on the recording. Leaving the Input set for DVD recording on the timer (like for recording overnight) doesn't work on PPV programs.

Make a single DVD from the VHS tape, and then with the aid of a computer, copy more copies. PC and Mac both have software that
come with the purchase.

Yes. However. I think this can only be done in DVD+R recording mode since you will be swapping out tapes to get to the desire sections. I would suggest having the VHS tapes set to the desired locations before starting to avoid searching in the middle of a recording session. Another suggestion would be to construct a single VHS tape with the various events and then covert that tape over to DVD. Of course that would require a second VHS recorder. Good luck.
