我用ATI MMC的測試工具
發現他顯示DX跟WDM有問題
WDM devices INF file not installed.
WDM devices are not listed in registry.
WDM devices are not loaded or enumerated by the device manager.
WDM devices are not registered with DirectShow

Test result: DX not installed properly

奇怪的是我WDM為啥會顯示這樣
感覺他沒有安裝到
我也換了數版的WDM
好像也是一樣情形
請問這是DX問題還是WDM問題
