yea this thread for some reason went wide. It’s might be someon’s copy and past. the forum now forces a limit for image size, can’t be bigger than 640x480 now.
anyways. difference between m3u and pla:
m3u : simple text file that display list of paths. can also display info about time and title that differs from the content’s original. m3u is supported in both MSC and MTP mode. you can create this with notepad or any text editor, and save it as a text file with extension m3u. can be transferred via dragged. also many applications can make and support m3u files.
pla: I believe its an xml, but I’m not too quite sure. pla is only supported in MTP mode. pla can only be created on the device. when WMP11 syncs a playlist in MTP it creates a pla file on the go, straight on the player. you can also create pla file using MTP (wmp11 drivers) by right clicking on the music that has already been transferred on the device and choosing create playlist. pla gets voided if you drag this file out of the player. just doesn’t work when you drag back in.
pla is very limited but easy to use. m3u can get confusing if paths are not done correctly.
