Audio but no picture, please help

[DaneClark]

I am trying to transfer VHS onto DVD using a TBC to color-correct it. Here's my setup:
-The input from my TV is connected to the output of my DvD recorder.
-The video output from my VCR is connected to the input of my Hotronic ap41 TBC
-The audio output from my VCR is connected to my DVD recorder.
-The output from the TBC is connected to the video input of my DVD recorder.
-The YC input of the TBC is connected to the YC output of the DVD recorder.

When I play the VCR, I get audio but no video. Please help me.

If I am understanding correctly then that bold part sounds like the problem to me.

It sounds like you currently have this.....

AUDIO: VCR---->DVD recorder---->TV
VIDEO: VCR---->TBC---->DVD recorder---->TBC

However, you SHOULD have something like this......

AUDIO: VCR---->DVD recorder---->TV
VIDEO: VCR---->TBC---->DVD recorder---->TV

If I am correct then it is obvious why you currently have no video.
