Want to understand unsupported format

Hi all,

I have a file with caracteristics below but I can not read it with my newly received WD media player 2.

General #0
Complete name        : Nessa.wmv
Format               : Windows Media
File size            : 723 MiB
PlayTime             : 24mn 30s
Bit rate             : 4124 Kbps

Video #0
Codec                : WMV2
Info                 : Windows Media Video 8
Bit rate             : 4038 Kbps
Width                : 1280
Height               : 720
Aspect ratio         : 16/9

Audio #0
Codec                : WMA1
Info                 : Windows Media Audio 1
Bit rate             : 128 Kbps
Channel(s)           : 2 channels
Sampling rate        : 48 KHz

I can convert it but I want to understand why it is not supported.

I have checked other files I have and got a few questions:

Is the WMV2/Windows Media Video 8 video codec supported ? (I thought WMV3 capability allow WMV2 support)

Is the 48Khz audio sampling rate supported ?

Thanks for your help.
