vhs to dvd problems

With the help of DVD decrypter and DVD shrink it's easy to back up DVD movies but I'm having trouble with the old VHS conversions. Capture with nero results in an 8 meg MPEG file. Nero says it can't shrink the file sufficiently to fit on a DVD. DVD shrink just gives an error message and won't accept the file. Nero says I must re author it but doesn't say how much of the movie I must remove.I need some kind of reference on describing each video file, it's properties, and compressibility to remain high quality.I notice commercially digitized versions of old movies are usually of excellent quality. Evidentally there are ways to compress these old movies and still retain sharpness and true colors. Suggestions? I bought a professionally digitized version of "Easy rider" and it was excellent, high definition couldn't be sharper.

the posted add for VHS to DVD delux looks good but at the price, $80, i'd like to see blue ray included. Most of it's features are included in several other programs I have already. Roxio does a fine job converting LP and cassette tapes to music CDs and windows movie maker, nero, roxio and sony movie maker platinum all have fine capture programs.

I think Nero will re-encode the movie to fit on a DVD without removing anything. Commercially digitized movies, I would guess, aren't from a VHS source but a Film source. I know that VHS looks like crap, and I don't think you can turn crap into silver with any technology. You said 8 meg, but you meant Gig right? (just making sure)
