Metathumb vs jpg

Hello all.  What are the pros and cons of both in regards to the Western Digital Media Players?  I do my “get info” from the Live Hub and then copy the files for my other hard drives connected to the other WD media players.

I have a WD Live and the Plus which do not like the metathumbs.  I tested changing the file extension of the metathumb to jpg and they worked on the Live’s, as well as, on the Hub and Streaming that I also have.  I am wondering if I should change all of them so that I am able to have the movie posters.  Any feedback is appreciated.
