Digital Workshop

Hello, I am preparing to use .ogg files for the first time ever in a publication (I like the .ogg files included with Opus Pro). I searched the forum to see if there were any threads about problems with .ogg files, and I found a few from January of last year in which publications wouldn't play the .ogg files without Direct X enabled. There are no posts after that, telling if the problem was resolved. I wouldn't use .ogg if these problems exist, because a I believe a good number of my viewers' PCs would have problems with Direct X. Does anyone know if the problem exists in the most recent version of Opus Pro?
Thanks,
Mike
