I'm writing for my friend, she's recently got a new computer with Windows Vista Basic preinstalled. Well she has a ton of WMV files she's downloaded over the years and none of them will play in Windows Media Player 11. It keeps giving her a error message saying something about the codec which I think is weird cause it's a default codec in Windows Media player right? Anyway, she's tried downloading several codec packs and even Media Player Classic to see if that would work but it was all to no avail. Another strange thing is that I downloaded a mpg and re-encoded it to WMV with Windows Media Encoder using my Xp machine and it plays fine on her computer. Is there anyway to make the other WMV files work on her Vista Machine?
