My understanding is that Flip4Mac will only play WMVs up to WMP9? If your files are WMP10 or 11, then I don't think Flip4Mac will handle them correctly; so, be aware of that.
i have flip and vlc, flip wouldnt open the file and vlc played it but it was all distorted and i couldnt see anything. I checked and found out you need wmp 10 or higher so i guess im S.O.L...thanks for the quick responses...if you have any other ideas let me know.
