TCX Flash Redirection/Accel Not Working?

TCX Flash Redirection/Accel Not Working?

I downloaded the TCX 5.1 suite eval to see what kind of performance gains it might give us with Flash but I don't believe it's functioning and am not sure what to check at this point. Here is my setup and what I have done:

Thin Client is a V10L (for testing, we have some newer models coming soon)
WTOS 7.1... (not at the office right now so not sure of the exact revision)
Connecting to a XenDesktop 5.6 Farm
My Desktops are Windows 7 64-Bit
Using IE 9 (32 bit)

I installed the 64-bit suite on the Windows 7 virtual desktop selecting the flash and multimedia components. In the configuration tool I verified that Flash Redirection was enabled with the Flash Acceleration fallback also enabled. DisplayW is set to true.

When I play a YouTube video, I see no performance gains - I also do not see the yellow W.

I didn't make any changes to my wnos.ini file as it's my understanding that a license file is no longer required for the eval.

Any thoughts on what I should look at?

Thanks in advance for any help.
