NTSC-J, PAL, and SECAM TV Tuner Hotfix for DirectX 9.0b on Windows 2000, Windows XP, and Windows Server 2003 (KB825116)

http://www.microsoft.com/downloads/...d0-b4310675b02b

DirectX 9.0b was released on 7/23/03 to address the MIDI security issue identified in bulletin MS03-030. A small number of non-security fixes were also included in the release. One of these fixes caused several TV Tuner capture card/driver combinations using video formats other than NTSC (NTSC-J, PAL, SECAM) to no longer initialize correctly on Windows 2000, Windows XP, and Windows Server 2003. Symptoms include loss of capture functionality and potential inability to set/retain device capture settings. This hotfix, documented further in Knowledge Base article 825116, has been issued to correct the flaw.
