I don't use InCD anymore as I suspect it caused a lot of the record & playback probs I was getting. It formats (it says) in 3min whereas Imgburn takes about 15 and doesn't recognise a format done by InCD and always wants to format again.
Other forums I visit always recommend removing InCD because of, as has been said, conflict issues esp with Roxio. It even needs its own clean tool to remove and it causes a lot of burn failures with Nero - very odd as its part of Nero.
Before I started using Imgburn I burnt with Nero and had loads of playback problems. Thats why using Imgburn came a such a pleasant surprise. It burns a lot quicker than Nero, even when its being held back to 8x on 16x media, with no burn failures or playback probs. All the focus with Imgburn is on the burning, with its formatting ability being overlooked, but I'm starting to think this is a major strength of the prog.
So my advice, and this is really bizarre considering where we are, is remove InCd and reformat all you RW's with Imgburn. Also, I don't know if you guys have tested Verbatim +RW, but the quality is not as good as their +R. I gave up on them and switched to Phillips...
