When you play Windows Media Video (WMV) files with Windows Media Player 7 on a computer running Microsoft Windows 98, stuttering (freezing of frames for a period of time) may occur.

When you play the same content on a computer running Microsoft Windows 2000, this problem does not occur.
There are periodic spikes caused by the SDK's ReadPacket function.
