DVD Ripping DRU-720A

I’ve had my DRU-720A for about a month or two now and today it seems that any DVD I put in rips at .2-.3x. When i try to run nero cd/dvd speed I get LC-UNRECOVERABLE ERROR 031105 on any disc i put in. I’ve uninstalled my IDE drivers in Windows XP and also cross flashed the lighton drivers for the 1673s and still it rips incredibly slow in dvd decryptor. What happened??
