We have several of the TMC-7DSP cameras here that we use mostly for training. Most of the cameras work fine, however a couple of them give random acquisition errors like you are seeing. There is no special camera file that I know of for this camera. You might want to contact Pulnix and see if there is anything unusual about the composite output on this camera. They might have a better idea about what analog settings would fit their signal best.
I have also used the RGB ouputs on this camera with no problems.
