Wonder if anyone can help me out.....I have just received a training cd for a job I am starting.....watched one of the videos, which is on cd, on a regular laptop running on windows at the office....had to watch the second video and they let me borrow the cd to watch at home. Well all I can do is watch the cd with no sound. It is a WMV file and I have flip4mac and quicktime running just fine. Any suggestions?
