Software is up to date. Can view pictures and audio files also play fine. However, attempting to navigate to folders which only contain videos prompts a 'please wait' message and then nothing happens. It doesn't navigate to the folder.

A quick Google search says it might take a while to load. I've waited for over 30 mins (the usb harddrive has about a thousand videos, total 600GB). The kicker is, I had the same model (which had a different fault and was returned a few weeks ago) load the usb drive perfectly well and it was able to play the videos within ~10 mins. I didn't add or change anything on the hard drive since.

Anyone experienced anything similar? If you have ideas on how to resolve this please share.
