I'm not new to computers, but I'm pretty new to mac so please forgive any stupidity on my part. I have a new iMac and macbook pro that I'm having the same issue on. I have some study videos I very much need to view but they are in .wmv format. I installed flip4mac but I only have video output with no audio in QT and VLC. It seems like it might be a codec mismatch but I can't seem to find any additional wmv codecs. FYI- these videos are only offered in wmv format so this is my only option short of converting the files to another format which I would rather not do as there are a LOT of videos and it will take me days. Thanks for any suggestions on how to resolve this.
