Problem making DVD data disc



I have a slight issue with trying to create a DVD data disc in Sonic RecordNow! ver. 7.22. When the step comes to verify the disc, the time jumps from 3:22 to 22:30 to 44:59 and so on. It only gets about 25% done when I see a dialog box stating “One or more files did not compare to their originals. It is recommended that you try and create your disc again.” Try it again, and it eats another disc. What could be wrong?

I’m using Memorex DVD+R RWs on a Sony DVD-RW AW-Q170A drive and trying to burn the DVD using Sonic RecordNow! ver. 7.22
