HTH

i was able to install and play file with WVC codec in Windows Media Player 9. After download of codec i had to reboot system and after it i was able to play it.

But that video is in fullHD. you need a really strong processor for it. Also i experienced error when some HD formats were unable to render in some video players. the reason remained unknown to me, but it is possible that it is connected with HD quality - some renderers and filters are unable to handle so much pixels.

How do you know if you need this?

If you intend to play HD video in 9x you're crazy anyway, so you most likely won't need it.
