dvds out of sinc

[dvdmaker]

To buy a set of dvds isn't cheap,and this is the second time this has happened to me that I'm watching and the audio is out of sinc with the pictures.The 2 dvds in question are Leave it to Beaver season 1 and Bob newhart show season 2.
Has anyone else come across this problem,if so can we have a list drawn up of shows that have this problem

season 11 of Frasier- my friend had the same problem with it but nobody online seems to have the same problem.
