Coverting AVI files to DVD Quality to Burn to a DVD Disk?

I know Techspot does not condone illegal services, but I had a question. I transfered a bought copy of a dvd to my computer and now I've lost the DVD but it's still on the computer. Is there anyway I can convert the AVI file back to DVD files and place it back on a DVD disk?

Can anyone explain how?

Well I just bought VSO's ConvertXtoDVD and its superb.

It cost me £24 but worth every penny, Im very impressed,

anyone know any free pieces of software to do this?
