I have been using both programs and usually--- what one can not copy (with AnyDVD running) the other can. However Hairspray stumped them both. It may be of interest that I was able to play some files using 1 Click on Hairspray but no files using CLone DVD.. Anyway, not a bad record.... thanks to SlySoft I have quite a collection of movies. Keep up the good work... this Hairspray is the first one I have not been able to copy in years. I would be interested in readers comments on 1 Click and CloneDVD .... I think they are both useful.
