I think I have most of it figured out...the Blue Ray plays MP3 music via USB ona thumb drive---not the actual MP3 device. I "thought" I could plug in the MP3 device/play direct thru Blu Ray, but cannot. I put in a thumb drive with photos, and had one song in mp3 format, and works fine.
NEW challenge: all the songs on my Mp3 are in WMA format (Windows Media Audio), so is there a way I can convert them to MP3 format?? If so, then I can transfer the music from MP3 device to thumb drive, then play via Blu Ray.
Also, going forward to download new music, how do I get into Mp3 format??
