Problem to see and hear some videos in avi format and VMW in WD HD Media Player GEN-2

Hi i have a lot of problems

I have trouble seeing and hearing some videos in avi format and VMW.
I get a mesage saying it  Unable to play the selected file.  Please refer to the user manual for a list of supported file formats.

I saw the latest version of the firmware in the following  link:

http://support.wdc.com/product/download.asp?groupid=1004&lang=ls

But I have the following version :  1.01.79 

WD has in your site version 1.01.77

Please somebody can help me on this.

I have WD HD Media Player GEN-2

THANKS,
