Connect your Mitsubishi HS-U69 to your Panasonic DMR-EZ48 using S-Video and R/L RCA audio cables. Put your tape in the VCR. Press record on the DVD recorder, and then play on the VCR and let it go. You will get one continuous recording with no chapter marks. No need to mess with your original tape at all. The quality will not suffer, at least not noticeably.
