Okay, sorted. I copied 3 .mp4 files to the ‘Download’ from my Mac to FVP-5000T. Just used the file manager (finder) as I was able to see FVP-5000T under Network.
I then went into the FVP-5000T and moved the files from ‘Download’ to ‘internal HDD’ . Checked if I can view them on the telly, no issue.
