I have burned several movies, and have never had a problem burning until now. For some reason the burning process has slowed down alot on my computer. I use DVD X Copy and dvd shrink to burn my movies, and it usually takes 10 to 25 mins. to burn, but for some reason lately it takes well over an hour to burn no matter what program. I have adjusted the write speeds in both programs to 8x, which is what the dvd+r's that I use are. Any suggestions to speed this up???
