Video capture device for senior citizen
The worst part of transferring old VHS to DVD is that it has to be done in real time as VHS is linear access and analog. Here are two ways I know of that work. One will eat your time the other will eat your wallet.

1) for about $35 or less you can get a transfer device which connects the output of your VHS machine into a USB interface to your computer. There are a bunch of these out there, they are all about that same as this:

It comes with software to capture the VHS program and "software included to burn full screen video capture, edit and create DVD" but you can take the captured mpeg files and put them in any video DVD authoring suite too. The software is easy to learn, you can start transferring quickly.

I did this process 3 years ago, I must have saved over 50 VHS tapes. So the cost was less than $40 but I surely put more than 40 hours into that project.

2) Costco and many other large chains have video transfer services, e.g.:

Prices range from vendor to vendor, $9 to $20 per transfer.
