Hello.. Please help. Will not play MP4 or mkv file ? Options

[DanWDTVLP]

Hello I just bought my WDTV live plus in hope I could easily watch the videos I have on my TV. I looked up the supported formats and it says thatit supports h.264/MP4/mkv etc..

When I go to play the file I just get the little circle going round 'n round and nothing happens. I tried another video I found on the internet and that worked.

Is there anything I can do to fix this ? This is extremely disappointing as all my video files from work are in this format ( most of them at least ). I hope there is some easy fix/way around this ?

Not sure if this will help or not, but I found some different specs on some of the videos.. here they are:

Total Size : 3.55 GB

Video Codec : 2-pass H.264 (.MP4 Container)
