I'd encountered installation problems with the previous version of the Player but version 7 installed first time without any errors.

KMPlayer

The KMPlayer is one of the best media players available. In fact I think that it's the only media player that can deal with the .nsv format. The new version can be downloaded from here, I suggest you get the 1432 R2 build.

Mathematica Player

I've had a total nightmare trying to download the Mathematica Player from the official site. Neither the Windows version nor the Linux version worked. Whenever I tried to install them they complained about a corrupt installer or the md5 checksum failed.

I managed to find this site where I downloaded a working copy of the player.
