Can I add my own codecs to the encoder?
The encoder does not support the addition of custom encoding codecs. However, the file you use as the source of an encoding session can be compressed with any codec, provided the codec is installed on the encoding computer as one of the following: DirectX Media Object (DMO), DirectShow filter, Audio Compression Manager (ACM) driver, or Image Color Management (ICM) driver. A good way to see whether a file can be used as a source is to try playing it with Windows Media Player 9 Series.
