I've been posting for a while on the Plex forums about "missing mp3 folders" and why plex doesn't seem to see them. Basically, certain CDs in my music folder show up in the Music Plug-ins "Itunes" plugin, but not the actual plex Music section. I thought I was going crazy watching plex scan my library and pass over certain folders and files time and time again so I thought I would try a little experiment. I tried to find any similarities in the actual mp3s plex keeps ignoring and I noticed that any CDs with a 128 bitrate were the ones not being seen by the media manager, so I used a free little mac app called "Switch" and bumped a folder of 128 mp3s up to 192, hit the refresh button and bingo, plex finally saw it. I'm guessing that plex ignores any CDs sampled with a 128 bitrate. Is that correct or was anyone aware of this? I like to think that this is a bug that can be addressed. I would hate to go through my entire library looking for any CDs that were sampled at 128 and convert them just so the plex Music section will recognize them!
