I have vista home edition and have noticed that every now and the windows media player will not work.If I click on the icon nothing happens nothing is reported in problem reports and solutions and if I reboot the system it works fine, could any one suggest what may be causing the problem? Many thanks in advance.
Ran system file check as advised by Crossbow7 no problems reported, my problem is Zeppelyn when this happens I am unable to view video or play music even from within a folder! I have to reboot the machine.
I have no solutions for you I'm afraid, I'm only responding as I had problems with Media Player on Vista before upgrading to Windows 7. Firstly it wouldn't play WMV files for some unknown reason, then it progressed to crashing sometimes when DVDs where inserted and autoplay was initiated, then for some reason it wouldn't play all the sound when a DVD was created with Nero 7.
Nothing I Tried, or read would rectify the problems, in the end I had 3 or 4 different video players on Vista to play my media.
You can try reading through this page for possible solutions (click here) you never know you may find an answer.
Good luck, I myself never found a solution for my Media Player woes on Vista.
