Converting VHS to DVDs

I been wanting to do this for some time as certain movies have
not yet hit DVD, but the system I initially tried it on couldn't
handle the data rate and produced garbled results. Anyone know
if there is a minimum system required for this to work well?
The idea would be to feed the VHS output to a capture card of
some kind, burn it to the hard drive then transfer it via Nero or
something to DVD.
I'd rather not buy a product pack that will only do a marginal job at
best.
