I have some videos filled onto one DVD+R, with using RecordNow and Nero, i have been making copies of them, no problem. The time ususaly takes about 15-20 mins on 4x to burn a copy. and now all of a sudden, the amount of time it takes jumps up to 45 MINS!!!!! for a single copy, still using 4x i tryed nero and record now, both programs still take about 45 mins to make it. why is this? and how should i fix?
