I have nero 126.96.36.199 and dvd shrink 3.2 memorex dvds and an hp 740 dvd writer connected with a usb cable. Nero always seems to work copying the files, but most times the dvds will not play on the regular dvd players I have in the house. They will play on the dvd player in my computer though. Everything is set up as default and I just let dvd shrink figure the compression and speed. Any ideas why they won't play on at least one of the several dvds I have in the house?
