Ive recently purchased100 Verbatim media based on reviews etc that said they were great.I have now attempted about 12 burns of which only 2 were completely fine,the majority returned failures as soon as they were first accessed during the burn process which Nero said was: ERROR cause: 129 (neroapi_call_failed) source: NeroBAOOpenFile() returned error condition description: _BAOContext::OpenFile() I have had a few succeed but when i play them the sound and vision are totally out of sink! Please could someone advise me on this problem,i know i will probably get moaned at for posting in the wrong section but iove never had much of a problem with using Nero 7 and certainly nothing on this scale. Could i have bought a dodgy media batch? Is it that i have to change a setting on my Nero for use with these disks or perhaps my burner is the issue.I would reeeally appreciate some input from you guy's if poss.Cheers.
