Hi Hope someone can help. I have a Sony DRU-500A, using DVDShrink and Nero 18.104.22.168. I am consistently getting the error 'The recorder does not support this type of disc!'. I have tried SONY DVD-R, Fuji DVD-R, Verbatim DVD+RW with no luck. However, once in awhile (1 in 25) the recorder accepts the format. Any help appreciated. I am willing to change software if anyone has any suggestions. Thanks.
