I'm sorry to hear your video and audio are out of sync. Usually when this happens to me, it's relevant to the streaming speed and Internet connection. Here's a link that helps describe how to get the best possible connection for your Watching experience.
Hope this helps,

thank you for your response however, i am still having the same problem but it only happens with the boxee box. I use the slingbox website, ipad app, iphone app and the slingbox player and they are all fine. It's only when i use the boxee box that there is a problem....where the video after 5mns of use starts to fall behind the audio, making it unwatchable. will this be an app error? faulty boxee box??
I am having the same problem with boxee box. When watching from PC is fine. Closing the SlingPlayer app and openning it again solves the problem for a while, then problem starts againg and video lagging audio deterioriates more and more as time goes by. All points to the boxee box's SlingPlayer app. Need a fix. Watching like this is getting very annoying.
