MP4 Codec ID = 20

[Wolfgan]

I'm puzzled with some MP4 files encoded with Codec ID = 20 (ie http://downloads.opencastproject.org/me ... senter.mp4 ) which in PC based players decode with same codecs as mpeg4. My renderer is a PS3.

Is there any way to force serving this kind of files instead of transcoding? (ie adding "20" as codec ID in Supported section of the PS3.conf file, or forcing the mime type somehow)
Thx for any tip, Wolf.
