Recording from tv with a unit which does not have a builtin tv tuner

Being the electronicly uninformed person that I am, I recently purchased a Zenith dvd/vcr combo recorder which I came to find out did not have a built in tv tuner. Does anyone know how I can use this product to record from my tv? I have heard some say that you can use a tv tuner in a seperate vcr. I have heard some say that I could buy some type of converter. I don’t know where or how. Please, throw a drowning man a rope. Thanking everyone in advance!!

I do not know what type of TV you have or how old it is, but if on back or front is any Video, Audio output, than that is where you will hook up your recorder.
If you use a cable box, than there is one there for sure.

The converter boxes (I am assuming you are in the US) for the digital switchover are tuners. They will pickup digital tv signals and convert to analog that your unit should be able to use (and switch channels for you etc). IF you are in the US, you are going to need a converter box anyway when things go digital in a few months (to record to a vcr, analog dvd recorder or any other analog device from broadcast tv). There may be coupons left for 40$ off (you can get 2).
In case you didn’t know, in about 5 months, analog tv signals will end in the US (for the most part) so you will need converter boxes anyway unless your tv’s have digital tuners.

Most major electronics stores carry them (for now anyway).

Fyi yes you can use a vcr too (at least while there are still analog broadcasts). IF you have cable, dish etc, you should be able to just change channels on their equipment.
