I picked this up right as BBS released it, at the time it was one of the best options for HDMI AND Component output with Optical audio out. They've since moved on the the XEDUSA+ and other models, but this is still a solid board. From their website way back when:

Xedusa borrows its name from Medusa, the eight headed epic creature in the Greek mythology. It is a plug&play advanced High Definition Pack for the original XBOX console. It's compatible with all the XBOX revisions from every region. It allows connecting your console easily to the modern HD TVs. It has both HDMI and Component(YPbPr) outputs as well as analog and digital audio outputs for maximum compatibility. It supports all the video resolutions from 480i to 1080i. It can output pure digital audio(direct from the console's SPDIF out)  via HDMI, Coax or TOSLINK optical outputs or analog stereo audio via RCA jacks, so you can hear the sounds which you have never before and enjoy more from your console. Also it can be used in a dual display setup by connecting HDMI and Component cables simultaneously, so you can play, record and stream at the same time, thanks to a built-in special video amplifier. This feature differentiates it from the other solutions. As it doesn't use any cables for plugging to the console, there are no losses in the quality of both video and audio signals.
