I have two Zinwell ZAT-970A units, and I'm having problems with both of them. The reason I bought them is because they can be programmed to pass programs to my VCR's.

There are many problems;

1. They do not always pass a good signal. My home has a TV antenna, with a signal booster, in the attic. On my main set-up, I have a splitter attached to my coaxial antenna cable. One signal goes to a Insignia Converter box which then goes to a A/B switch and then to the TV. This works fine. I need this set-up because we will often want to tape a show while watching another show at the same time.

The second signal goes to my Zinwell ZAT-970A unit, then to my VCR. The VCR is connected to the A/B Switch which then goes to the TV.

My problem is that my Zinwell units will, quite often, scramble the signal, sometimes for a half hour or more. It will also say "BAD SIGNAL" or "NO SIGNAL". At first, I thought I had a problem with my antenna set-up. But then I found out that, after switching over to the Insignia converter, the reception is fine...the Insignia box is not having any trouble with the signal quality or strength on any channel.

2. Once the Zinwell converter box has encountered what it thinks is a bad signal, everything is out of sync. Even if the picture clears up, the sound and the picture no longer match. The sound lags by 3 or 4 seconds. If this happens while you are watching, you have to power the unit off and on to get it back in sync. If it happens while you are recording a program, you are out of luck.

3. Another annoying habit that the Zinwell units have is that, every once in a while it will not start recording the program (channel) you programmed, it will jump to the last channel in your channel list and pass that channel to the VCR. Then, when you get home, surprise surprise, you have a recording of some obscure show, on a channel you never heard of.

4. We use closed captioning a lot. When you play back a program you recorded through the Zinwell box, the closed captioning is totally scrambled.

I purchased these units back when the initial HDTV switch was supposed to happen in January so my warranty may now be in question, but I need to get these issues resolved before the new season begins.

I have tried their Customer Service number 1-866-444-3739 many, many, many times. I have never been able to connect with anyone at their "CUSTOMER SERVICE" or "TECHNICAL SUPPORT" extensions, EVER. Go ahead, you try them. Do it BEFORE you buy. I sent emails to the two addresses they list on their web site. No answers so far. Are they still in business???????
