Hello all, I am the newblit here first post just registered today. I apologize in advance if my question is in a thread, I did search. I have read many of the guides here and am still a bit lost. Home built comp: Mach Speed msnv 939 AMD 64 3.7 2 gig DDR ram windows xp pro Drive: Plextor PX-800A Media: Ridata 8x dvd+r DL TDK 16x dvd-r Software: dvd-cloner IV ver4.30 build 918 I am trying to back up a movie. I tried to make it originally on the db5 dvd-r i have, but couldn't because of the size. No problem, got the dvd+r dl. Did the read and burn without issue, put it into the dvd player and "dirty disc" message. checked the disc and its fine. First disc was in read i/o spti. While typing this I just finished the second burn, did this read in read i/o aspi. Just popped it in the dvd player and it works fine. My question is did it not work the first time because of my media? read i/o? Or was it something else? Even if no one answers me cause it's a repeat Q I want to say thank you guys for an excellent forum and site. I have trolled this site over the past couple of years every time I have had an issue and always found the solution here.
