Wyse Xenith 2 Beta 2.1_019 firmware upgrade issue

The latest firmware release does wonders for the video performance on the Xenith 2 (even though no flash redirection updates are provided for the Wyse T series). One major problem is that any Windows media player file will not stream; it stalls at the very beginning of the video and remains stuck. Downloaded WMP files, on the other hand, will play just fine, so it's only related to the streaming aspect.

Has anyone else seen this and when might we expect a fix? Otherwise, this is the best release in at least a year as far as performance goes, and highest time.
