But yes, that should work fine. [/B]
If it were an audio CD it would be wiser to use your original, however when we're talking about a DATA DVD or Video DVD (which is DATA) he should have no problem making an ISO of that DVD+R copy and transfering it to another DVD+R, to answer his question, he will not transfer the problems to his new DVD+R providing the initial data is not corrupt. I've seen cases where the DVD+R will cause problems on a given DVD Player, due to the media type, but usually the same DVD+R can be read by your DVD-ROM without any problems, even with high PI/PO.
I can read DVD+Rs with PI/PO that sky rocket past the specs and they are 100% readable and compare bit to bit to original DATA. These discs may cause problems in some DVD Players however.
As long as the disc is not in a bad condition that make its sectors unreadable or damaged to a point of corruption you should have no problem.
