Reddit mentions of Funai Combination VCR and DVD Recorder (ZV427FX4)

My videography company does this for people every day. The easiest way to do it is with a VHS->DVD recorder. You just put your cassette in there, put a DVD-R on the right, and record away.

Main things to remember about that process:

1. You need to finalize the disc when it finishes recording
   
2. You kind of need to know the approximate duration of the tape before you start, so that you can select the right record mode on the DVD.
   
3. Use DVD-R, not re-writeable or DVD+R. Makes it easier to ensure it will play back in any DVD player.
   
   Now, you said some of your cassettes are small? They could be either VHS-C or some kind of 8mm cassette. For VHS-C, the easiest is to buy something like a VHS-C Adapter. You just put the C in there and plug that whole thing right into the VHS player/recorder.
   
   For 8mm tapes, we try to use an 8mm camcorder. You can find them on eBay or possibly at a second-hand store in your own city.
   
   Any other questions?
   
   EDIT: One other suggestion... Put your finished DVD into your computer and copy the VOB files to your computer. Maybe even upload them to Dropbox or something. That way you have digital backups in case anything happens to that DVD, or if twenty years from now we don't use DVDs anymore.
