It has been a bit over 3 months since there has been an update to InCD.

Is that a sign that InCD is now more reliable than when I stopped using it in February?

Are there still known problems?
What about with Win XP SP 2?

IMO it has. There are still some speed issues with DVD-RW and DVD+RW media though. For whatever reason, its still much slower than say Drop to Disc or DLA.
