trouble with Audirvana and multipl artist tag

[pask]

Thanks Paul and Beck for taking the time to get back to me do appreciate it a lot
Yes, using multiple platform with complex tagging ( gendar + composer + all artist ) is actually a nightmare :,(
BUT, i do like a lot the way I'm using my NAS + MacBook Air + audirvana(DLNA version) + DLNA AMP, very fast and flexible, on the same time, NAS + Minimserver + iPad + DLNA AMP is so cool and computer free and has a better WAF factor

After doing some investigation, and converting files in different format, I just found out that Andirvana tags are correct via minimserver on all artists tag on files converted to FLAC files. When opening a FLAC file in MP3tag, correct separator are displayed \\, and it works via both platform perfectly... But the same file in M4P version return me ;;;; for miniserver on the all artists tag .... I can't believe I've done something wrong as I ran this test on multiples album with multiples artistes...

A Lord, my collection is 70% M4P... should I really have to convert them to FLAC to get the good display on both platform ? :,(

Well the lazy option could be to only use artist tag when using minimserver on iPad and just forget about the all Artists one ... of course I can live with that

Thanks
