I updated Samsung 552H firmware from 08 to 10 and found that my Audio CD ripping speed reduced to 3-5x from 12-16x. So I went back to firmware 08 and the ripping speed came back up. All of a sudden I found even though Nero reported a good DVD burn, the DVD created was a coaster. Somewhere 1/3 of way the data would be irrecoverable on the DVDR, 25 DVDR down the drain! After buying a SONY DVD writer and finshing the job, I started to play with the Samsun drive and when I changed the firmware back to 10, the DVD writer became fine with no bad burns but the audio ripping speed dropped to less than 5.. Some you win some you don't..
