I'm having trouble playing low bitrate (seems like less than 400Kbits/sec) WMA lossless files. My M1000 just says "unable to play". I am using WMC as a server, and have the latest M1000 code loaded. I used WMP to make a playlist of all wma files less then 500Kbits/sec and I haven't found the cutoiff yet, but it seems like only the ones with bitrates higher than 400 will play. All the files play fine with WMP.
Is this a known issue? I suspect it is a problem with WMC.
Sorry if this has been reported already, but i couldn't find anything searching posts.
