Thanks for your reply grain. Mitsubishi seems to be a little bit cheaper over here in oz than verbatim are. I might try them.
Maxdata comes up as Ricoh in DVDDecrypter, but they seem to be a bit funny. The first 3 I used were great, but now the next 3 have come up with the IO error, and it is not correctable. Only in the verification part. The movie still plays fine on the home DVD player, but on the PC gets stuck after about 1/2 way through the movie. So I will try some mitsubishis.
Thanks again
