Safari gives “unable to create unique tmp file” error with embedded Windows Media

While attempting to build a cross-browser compatible embedded Windows Media Player web interface, I noticed that Safari began to give errors on browsing to any embedded video player. After weeks of suffering through thinking it was my bad scripting, I reinstalled Windows Media Player. It immediately started working again on non-scripted embedded video – in other words, if there is no special scripting or sami files, it will work.
