Thank you very much bpa. => Streaming as FLAC on a single player is OK. => Steaming as FLAC when synching several players is "choppy" at the begining of each tracks . Is it a bandwith limit or a CPU/Mem issue ? => Using "Bit rate limit" (lame) option seems to cause CPU overload (my hardware is a 500 Mhz CPU NAS). I'm not understanding well the SC settings > advanced > format UI, see screen capture. - Why AIFF and MP3 type are greyed ? - How to choose between format types ?
