strange problem with that file. When I play it in Windows Media Player and Zoom Player I don't get the surround right or left. I only get right, left, center, rear right, rear left, and lfe. I have ffdshow configured as the decoder and my computer which has an ATI 4550 is plugged into an Onkyo 806 via HDMI. The Windows speaker test plays fine on all speakers. Did I miss a configuration in ffdshow? I am using revision 3026 and during installation I selected 7.1 channels.
