Video delay on The Klipsh Three using Play-Fi HD

Hi!

I just bought the Play-Fi HD to use with Klipsch the Three (version 1), so that I could play videos: https://play-fi.com/apps/windows/

 

But, even with the HD version installed, and "video mode" selected I get the some "delay" between the audio and video of the file. I use a WiFi connection, and the problem is the same no matter which player I use. Any suggestions?
