"Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file."

When i view as thumbnails i could see an image of the all the files.
I have k-lite codecs installed, i have tried VLC Media Player...still doesn't work.
The files are located on various different hard drives which contain both working and non working files, so i don't think the hard drives are malfunctioning.
