I think I've discovered what my problem is - partly prompted by your and
Trev's replies. The test file I was using was 4.37GB in size according to
its properties, which should have fitted ok. But I see that Wikipedia's DVD
entry says there are two ways of expressing GBs - and that in the one PCs
use, 4.37GB=4.7GB as far as a DVD is concerned. First I'd heard of that.

So now I've been progressively frame cutting the file until it recorded ok
as data. Success occurred at about 4GB in PC properties terms (i.e. 4.2GB
was still too big). So I guess that's the safe limit for my video file
archiving.
