Try
http://www.oldversion.com/program.php?n=wmp for Windows Media 5-7 (sorry NO 8) I love
http://www.oldversion.com it is full of great stuff
WMP9 is doing funny things...
Say a video is 540x362 (MPG)
Open in WMP9 & see the File/Properties & it shows as 640x362)
Anyway... I use BS-Player (FREE & Easy). Hit P & it saves a JPG for you
