So I have xbmc running on 3 different machines. My iMac, atv2 and my windows 7 acer revo. My setup is this:

All files are stored on my nas. Which is shared via smb to my 3 machines. My files are a combination of .avi, .mkv, .iso, and .m4v. My iMac xbmc plays the all, atv2 only plays everything apart from the .iso and windows did play them all also. So I wanted to get all the files to work on all machines so I converted the iso's to m4v and that worked great. My atv2 now play them all. But now my windows 7 xbmc doesn't play them apart from one file?? It loads the file as normal but just goes to a black square in the top left corner likes it's about to play a trailer. So what have I done wrong? I know my revo has bad wifi so I assumed it may be buffering but I left it for shouts and the files still don't play.

Any ideas?

Thanks
