I can't say I've seen a situation where Windows Messenger 5.0 video capabilities don't work,
but they do in 4.7. If you just upgraded to Windows Messenger 5 and voice/video simply
doesn't work now, try using System Restore (I assume this is your own computer) and restore
back to when 4.7 was installed just to verify that it still works in 4.7. To do so, click
Start, then Help & Support, then "Undo changes to my computer using System Restore" and then
restore back to a prior day when 4.7 was installed.
