barkmoss you can't delete the files b/c they were being shared. You will 1st need to close LW.
As for WMV for mac.
yerk!!! My WMP works fine xcept too many files don't have the appropriate codecs to play on a mac. doh! Typical M$! They wouldn't think about that would they! WMV files IMHO are not worth the effort. Due to their DRM or whatever it's called allows for viruses, spyware, spamware, & links to advertising sites. Just for WMA see:
Doh #1 mistake by W$ , & then
Doh mistake #2 & that's only wma. wmv is equivalent. What's more wmv quality ain't that great anyway. If you really need to play wmv files, use VLC (a free player that has inbuilt codecs & plays everything xcept the odd wmv file):

M$ rarely update anything that's for the mac (xcept Office). That's how deep they think about wmp issues for mac users. (skating on the thin ice of the new day.) Typical Windows error problems; 'new' error list just come to light:
Doh! lol
