I have a CT-200 connected between a Sanyo HI-FI 4 Head VCR & a Magnovox MWR 10D6 DVD Recorder. I can copy commercial VHS tapes about 50% of the time. Mostly WB, MCA & HBO produce the error message, although some of these brands copy also. Looking at the simplicity of the CT-200, it seems pretty difficult to connect it incorrectly. I was hoping for a better succes rate. Any suggestions?
