If all you have is the VHS, then you should really get the DVDs. For those of us who own the LDs and a LD player- the benefit is less clear, but even a non-anamorphic transfer will be a huge improvement over VHS, for a lot less money than you would spend on the LDs and a decent LD player.
Even if you have the 04 DVD sets already? and BTW, I dont think I have a widescreen computer (it's a gateway)
