Constant buffering during movies when using Bluetooth earphones

Hi, and thanks for the great software!
I’m experiencing an issue if I use bluetooth earphones when watching (well… actually listening…) movies with Dolby Digital audio.
During playback, movies stop to buffer audio every 2-3 minutes (5 if I’m lucky) and makes impossible to enjoy the movie.
I tried to forse AppleTV’s audio to stereo (no results), to use the Passthrough option of Infuse (again, no results).
I’m not experiencing the problem with TV shows or, more generically, with video files with a standard stereo audio stream.
No other video\streaming apps show the same problem.
