Ver. 1.90 has major breakage -- they removed WMV1 support from their .WMV video converions, rendering it unusable for the Zune 30.

The built-in Zune support does NOT work with the Zune 30, but up to ver. 1.85 the "all to WMV" option could be used, so long as the encoding was set to WMV1. Now, with no WMV1 option, it can not be used. I wish they had not removed that option -- I was hoping that the fixes they say they made to aspect ratio calculations would fix the problems I've experienced with some 16:9 source material, but it's moot since I can no longer use the product at all. I reinstalled 1.85 but I'm not real thrilled at this point. To anyone else using this for the Zune 30, be aware of this issue, ESPECIALLY if you no longer have the 1.85 installation files on hand!
