is it save to remove xml and jpeg files?

I have a synology NAS and a very happy aTV Flash user.

Sadly I get more and more problems loading files from my synology NAS.

In the begining I selected a file and almost directly it loads the movie.

 

Now I have to wait until it is finished buffering and when I pause the movie it has to buffer again.

When I look on my NAS I see lots of xml and jpeg files which might explain the problems I am having.

Is it safe to remove them?

I mean does the aTV Flash recreate them after they are deleted?

 

This way I can rule out it is because of these files I have. (There are about 10.000 files in total which aTV must load.)
