Would it be possible to know how does the firmware synchronize audio and 
video (PTS ?, DTS ?, other ?)
1) during reception
2) during playback
and what is the maximum time distance between audio and video after 
which audio or video is not output
1) during reception
2) during playback

This would help us [me] to understand why the sound is sometimes missing 
during reception and how to feed better the audio and video data during 
the playback.
