Your digital converter box probably does not have an analog pass through that allows the old analog channels to go through to the tv's analog tuner.

SOURCE: I have an RCA converter box hooked up to an RCA tv

Basically, you cannot use the coax connections for both the VCR and the RCA converter box. I would hook up the phono/cinch connectors from the VCR to the TV if you can (these are also called RCA connectors, but I'm avoiding using that name so we dont confuse the digital receiver with a cable/connector name that is the same here). There should be a yellow one for video and red/white ones for left and right stereo. I believe the RCA converter comes with a three headed cable that can do this for you. With this configuration, you can set the TV to input on these connectors and the VCR should always output there. Once that is set, you can still use the converter box to receive the signal from your antenna, then run the coax to the VCR. Now, the VCR will always have to be set on channel 4 in your setup and you will need to manually change channels on the converter box for it to record a show. Does this make sense so far?

SOURCE: My TV says

I just looked at a TV last night for this. I don't know what you've tried yet, but I was getting that message until I went into the menu and selected the automatic channel scan. I forget what it was actually called, but you'll find it. After that, 19 digital stations came in beautifully with a cheap set of rabbit ears. (The scan will also find analog channels, which you can delete later on.) Good Luck.
