DVD won't work on movies after upgrading to XP Home

[Karen]

I upgraded my OPS to XP Home version. When I put a DVD
in the DVD drive I get the following message:

"Unable to load the InterActual Media Playback language
file"

Please reinstall the product and try again.

The DVD player came on my HP Pavilion XT856 and it was
previously run on Windows ME. I don't know what I'm
supposed to install since upgrading. Can anyone help?

Thanks.
