You can do this in two ways:
a) If you’re familiar with computers and you want to spend some time for editing your videos to your PC, you can record each VHS tape in a DVD using your DVD recorder and then import that video to your PC. You better use a rewritable disc so that you can use it again. In this case, I would use the best quality the DVD recorder can offer. You can do this for all VHS tapes. Then using an DVD authoring program in your PC you can make a single DVD out of all video files, nice menus etc.
b) If you want something simple, easy and quick, you can record all VHS tapes sequentially, one after the other, in your DVD recorder in SP mode (2 hours recording). Just stop/pause the recording process and continue with the next tape.
