2a. Windows 95, 98, and Me: Go to your Windows folder and find the file named system.ini. Under the [drivers32] section (or create it if it doesn’t exist) add these two lines
2b. Windows NT 4, 2000, XP, 2003, and Vista 32-bit: Run the registry editor (start, run, regedit.exe). Navigate to the key HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/Drivers32. Create a string value named VIDC.BT20 with value btvvc32.drv. Create another string value named VIDC.Y41P with value btvvc32.drv. Navigate to the key HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/drivers.desc. Create a string value named btvvc32.drv with value “Brooktree ProSumer 32-Bit Video/411 Video Codec” (without quotes).

To check you’ve installed the codec correctly run VirtualDub. Click Video, Compression. You should see two BrookTree codecs listed.
