I've been having a load of trouble copying DVDs, I've followed all the usual guides and still have got nowhere. The problem is that whatever software i use to rip/re-encode/burn my writer gets stuck on 0%. I've updated the firmware, tried to install the latest ASPI drivers, used all kinds of new and old versions of the software (CloneDVD, DVDDecrypter, Shrink etc...). My drive and discs work fine when writing data backups etc... I really don't know what else to try. I'm using a new LG GSA4163B writer that can write every format of disc inc. DVD-RAM with Ritek G05 DVD-Rs or Sony DVD-RWs.
