I have used DVD shrink for almost two month now and was more than happy with the software. Until a few days ago: the avarage time for a back up (including analysing, encoding and back up)used to be between 50 mins and an hour. The reading rate was about 3.3 kb/s. From one backup to the other the avarage has gone up to 1.5 kb/s. No relevant changes have been made to either hard drive or DVD driver. I have also installed the latest DVD shrink software, checked for viruses, trojan and other malware. Any ideas? Thanks in advance.
