Can't Play AVI Video

I have tried to play AVI on my PC and I get audio, but no video. These files have worked previously on my PC. They play only audio using DIVX Player, Nero ShowTime and Media Player, all which have been used to play files in the past.

Any ideas? Thanks in advance.

 

Probably K-Lite will help...

Have installed K-Lite and still only get sound on Nero Showtime, Media Player and DIVx. Tried installing a new player and it works fine, though not a fan of the player.

 

Have also tried installing VCL and it suffers from the same problem. Finally tried DVD and it also has the same problem.
