I've been using Nero 6 for a while now & recently I have occured a strange problem. When I burn an ISO it used to take about 25 min (burning @ 2x b/c I cant find any firmware to burn @ 4x) & the timer would have an accurate time elapsed counter. Recently the timer will say time remaining 0:00 min but the burn process will be somewhere between 40 or 50%. Also the total burn time will eventually take 30-40 minutes. Ive un-installed the software & loaded a older version 18.104.22.168. I still have the same problem with this 1 as well. Any advice??
