While we can digitize it and possibly use a better digitizer there is no system short of editing it frame by frame to correct flaws.
If it's a sort of documentary my first thought is to keep the original from being full screen for too long but put it on the screen on screen like you see on TED where the presenter talks about the content.
http://www.youtube.com/watch?v=5riPKdpuoiI is a good example.

Hello fellow Cnetters! I need your help and insights. I have been in effect 'set a challenge' by a dear friend of mine, who wants to 'upscale' the low VHS quality of a dvd film that I have been 'running off' in its 'raw' state for her, over the last two years.
However although this dvd, original VHS format, was done in 1989/90, she would like to improve its quality from low level VHS to, what we are now used to seeing, which is HD quality photos and films.
The film was originally produced amateurishly, by someone who wanted to tell his story of how he became a Nichiren Shoshu Buddhist in the early 1970s, and went onto become world kick-boxing champion, at least three times..
It does have the qualities of a low budget self-made movie - but as I stated before, my friend would like to 'upscale', as an 'easy to understand'/popularist way of talking about Buddhism.
I had recommended to me, an 'open source/free download' version of 'movie editor pro'; however I am a real rank amateur - I have never done anything more 'complex', than 'cut and paste' and 'overlay' of pictures with some 'word 4 windows', font formats and clip art!
So please - help me, where and how do I start - and can one get 'easy to use' FREE editing software for 'vob, ifo, bup', frame/picture formats?
Thanks in advance, for taking the time to read and consider this request.
