I have a macbook Core Duo and I access WMV files on a windows machine through a share w/ gigabit ethernet. When I directly open any AVI file, any file that is NOT WMV it opens in quicktime immediately and plays perfectly. However, its when I open a WMV file, the larger the file the worse the symptoms, that the Windows system spins its hard drive like crazy and Quicktime literally takes 30 seconds to over a minute to open it. Also if the file is a few hundred megs or more by the time it opens my fans are spinning on loud, which means the CPU is going nuts, but the file hasn't even started playing. The quick solution to this is to open the files in VLC, but I rather like quicktime and would just prefer to use that if anyone has any solutions. Thanks
