Even if the company has gone out of business, they could well have sold their rights to various productions.
That said: VHS + DVD recorder + SCART = DVD copy. You may need a video stabiliser if the original has copy protection, and if you wanted you could then use various bits of software to "tidy up" and re-burn a "neat" DVD. You could also go VHS to PC, though PCs with the correct connections aren't common so you'd probably need another bit of hardware (and in both cases, quite a good PC) - so the DVD recorder method is much easier.
P.S. I would only recommend this method for otherwise unavailable titles, as (especially if you do the "tidying up") it is quite time-consuming and a lot of faff and the quality often isn't great (depending on the source material and your equipment). Not to mention that copying copyrighted material is illegal!
