Cannot connect the coverter box

Yes. Connect antenna to digital converter box and then connect box to tv antenna connection. Use ch 3 or ch 4 on the t.v.

Try this. You will need 2 RF cables and a RCA cable that has a red, black, and yellow plug on each end.

1. Plug the antenna signal into the converter box.
2. Connect the RF output (TV out) of the converter box to the RF input on the VCR
   
3. Connect the RF output (TV out) on the VCR to the TV
   
4. Finally, plug the DVD recorder into the converter box also, but use the 3 RCA cables that came with it (audio left, right and video).
   

DVD does not need to go through converter box.
The converter is only to receive the digital TV through the antenna. DVD might have to switch to another connection on the TV, and if it doesn't have enough connections, you have a problem.

It took some time, but I finally have this figured it out so everything works.

I have the same setup, but I had one additional piece to the puzzle that I had to figure out. I have an older TV and use and antenna, but had to buy an Audio/Video RF Modulator a couple of years ago to use my VCR & DVD player with the old setup.

Get yourself an Audio/Vido RF Modulator (you can pick one up for about $20-30).
Connect the TV to the RF Modulator.
You should have 2 connectors for your antenna. Connect one to the converter "To Ant" and the other to the RF Modulator.
Connect the convertor A/V cable to "IN" on your VCR.
Connect the cable from converter "To TV (RF)" to "UHF/VHF from Ant" on VCR.
Connect the VCR "OUT" cable to the RF Modulator.
Connect DVD A/V cables to A/V input on VCR.

Your TV should be set to Channel 3 (or 4, depending on your setup) and depending on your "input" connections, you should be able to view vidoes from VCR like this and DVD by changing the input (the button should be on your VCR or other remote). For ex. my input changes on my VCR from channels, to L1 & L2. My converter & VCR play on L1 and DVD's play when I change it to L2.

Now, I just have to figure out how to add the converter box to my universal remote. :)
Good luck!

instead of plugging in the rf modulator before the cable box, i plugged it in after it

Hi Karen, I think you are having connection issues. Can you provide specific details of the connections? Thanks, Mike

Yes you can first connect the converter box to the antenna first. Next hook the tv out on converter box to vcr in on vcr. Next hook the vcr out to the tv in and watch vcr and converter box on channel 3 sometimes channel 4.on the actual tv and of course change channels with converter box remote. For dvd player hook it straight to tv with red,white,and yellow cables that come with your dvd player. Then to watch dvd player if it's hooked up that way you have to put your tv on a input like video 1 or input 1. This can be done by using the tv remote and looking for a button that says tv/video or input or source button. This is some common names for that button on tv remotes.

Here is my setup.
1) Separate DVD player 2) Separate VCR 3) Digital to Analog Converter box 4) Analog TV 5) Rabbit ears (UHF/VHF) antenna
The antenna goes into the converter box.   The RF-output of the converter goes into the RF-Input of the VCR The DVD output goes into the front input jacks of the VCR The VCR RF-output goes into the TV RF-Input The VCR Line output goes into the front of the TV
To watch DVDs, we turn on the DVD player, turn on the VCR, and set the VCR channel to L2, and tune the TV to channel 3.  The converter is off.
To auto record on the VCR, the converter must be tuned to the station being recorded.  The converted must be turned on, the TV can be off. 
To watch VCR tapes, turn the TV and VCR on.  The TV is set to channel 3.  Just press play on the VCR.
To Watch TV.   Turn the TV and converter on.  The TV is set to channel 3.   Change the stations using the converter.
