Samsung TS H522U wont read INCDFS CDs

My sig shows the burners I have. My DVDRW burner, despite having Mt. Rainier reading capability, suddenly wont read InCD formatted CDs. It reads other CDs fine. It’s not a huge deal because I use my combo drive for that usually. But just wondered why this would happen? I tried uninstalling/reinstalling both the burner drivers and InCD itself…no change.
By the way, I posted this in the General Optical Drive forum but got no reply so forgive me for posting twice, but I see no way of deleting ones own posts.

Ignore, I gather this is an issue between different UDF packet writing softwares. If I InCD format using the DVD drive it will read them, but wont read ones initiated on the other drive…weird but I can live with it.
