I bought a new Seagate Expansion Drive, transferred what I could to it and have it set up on my Smart Tv, no worries!

I bought a 2nd Seagate Expansion Drive, copied everything to it and use it through the USB on my Blu-Ray player on my other TV (an older AKAI) and have problems...

The Movies I downloaded prior to September 20th 2014 work fine, the movies I downloaded after that have an error message from the TV/DVD player saying 'Audio files not supported' and of course, play silently.

I doubt this is anything to do with the HDD's and perhaps not with the TV or DVD player because it coincides with the date that I installed and started using VLC as my default media player. Could that have altered the files when I downloaded them so they won't play properly on my devices?
