I'm having the same problem with a img file, I tried it three times, 2 x CMC.MAG.AE1 and a Ritek G05 both fail on verify very close to the start. And sure enough when I use RecordNow MAX on a verify ONLY setting - they fail verification near the start. I used DVDD and it burned it to a CMC.MAG.AE1 and verified fine in both DVDD and RecordNow without any problems at all. I've also got AnyDVD installed but rarely use it, I've uninstalled it now and will give it a go when I've got something else ready to burn.
The failed verification discs play fine in my standalones...
