Did you have the wrong glasses? If the eyes are reversed you'll get the pop-in effect. Not every TV syncs the same way, the wrong glasses on the wrong set will blank the wrong eye at the wrong time...or something like that.

I turned my glasses upside down while bored in Avatar just for a change of pace.
