Any recommendations for a DVD? My most recent purchase of disks cannot  
produce a universally read copy. Looking around on the web I found a  
site that said that there is no relationship between the brand on the  
outside and the disk inside. It recommended a special software that  
would read the makers ID on the disk which does not help much if you  
have to buy the disk and analyze it to determine whether it is reliable.
