Problem with network sharing on my WD TV Live Plus

I have a WD TV LIVE PLUS. I have it set up with a wired to my router. I am have it set up so that I can read and play my movies from my PC I am running Windows 7 Ultimate. I have 153 folders and it only shows 88 and all of the movies are AVI I don’t understand why is it that the WD TV LIVE PLUS doesn’t read them. I copy the films that the WD TV LIVE PLUS doesn’t read I copy them to my USB Patriot 8GB the WDTVLIVE PLUS reads them off the flash drive. You help would be appreciated!..  

Is each movies in a particular folder or are you wanting the TV Live to read the video and audio folder?

The films are in each individual folder with subtittles…
