Oh, if only it was as simple as that! You have to go through a 2-stage process, firstly creating a video file on your computer and then burning that file onto a DVD.
I'm unaware of any standalone device that actually incorporates the tape player itself. Therefore, if you've not still got an old one lying around, the first thing you'll need is a secondhand VCR. (Around thirty quid on eBay).
Almost all VCRs were built with RCA outputs (as well as Scart ones). but it would be wise to check that any VCR that you're considering purchasing actually has them. (An RCA outputs is a set of yellow, red and white 'phono' sockets). Alternatively an S-Video output, which is much rarer, would also do.
Then you'll want something like this:

Unsurprisingly, you plug the yellow plug into the yellow RCA/phono socket on the back of your VCR, matching up red-to-red and white-to-white in the same way. Equally unsurprisingly, you plug the USB connector into a spare USB port on your Windows PC or laptop.
Such devices normally come with video-grabbing software, which you install onto your computer. (Alternatively they might come with a web link to something like VLC, which you then download from the net and install).
You simply open the software, activate the 'Record' feature and start the VHS video playing. Once it comes to the end, you stop the recording and save it to your hard drive (usually in MP4 format).
Then you move to the second stage, which is to burn the video file to a DVD. Modern versions of Windows include built-in burning software but this freebie is probably better:

(You'll also need to be using a PC or laptop that's actually got a DVD-writer built into it. Not all DVD drives can
write DVDs; some can only play them. Otherwise you'd need to purchase an external USB DVD-writer for about 14 quid on eBay).
You need to be aware that unlike 'ripping' CDs, there's no fast way to carry out the first stage above. You can only do it in 'real time'. So, if you want to transfer twenty 90-minute tapes onto your computer (ready for subsequent burning onto DVDs), it's going to take you 30 hours to do it!
