Un des points de la beta :
Peut être que ça améliorera un peu les choses (ou pas :^) )1. Improved the Audio/Video synchronisation when streaming from some cable TV boxes connected to the HDMI IN port (Front and Back). Customers have reported that with normal TV playback, if there is any change in the content audio format (for example, from Dolby Digital 5.1 to Dolby Digital 2.0), the audio/video outputs could become out-of-sync. This issue has been significantly improved upon in this firmware. (We are aware of an audio startup delay issue when switching from a Dolby Digital 5.1 input to a Dolby Digital 2.0 input, and we are working to resolve it in a future firmware version.)
