If the files are mp3, then you should be able to stream them. .AAC is a supported format for video files, but not audio files. You might try to rip a CD in mp3 format and see if that works.
I have just installed my Samsung C6500. I have connected the wireless network and can get on the internet-no problem. The problem seems to be the MUSIC function on the PC Share manager . I have downloaded the Share manager and I can get My pictures just fine on my TV, however I can NOT get the Music to work using the same process of Share folder/Set change state/share/set device policy process. I see the folder name on my TV when i enter the share manager from the main menu. I have also downloaded the updates for the C6500.
Could my itunes program be causing any problems?
