No, it uses the VIA K8M800. The CLE266 is the oldest chipset that had this. I believe it was more limited than the later chipsets (maybe this is the one that didn't support HD.. the others do.) There are several VIA chipsets that support the hardware MPEG2 decoding. From the unichrome source

The Unichrome integrated graphics chipsets are available on more than just Mini-ITX boards. VIA makes P4, Athlon, and even Athlon64 boards with the Unichrome video. This seems like an interesting option to me.It allows for the most offloading of MPEG2 processing, while still using a fast CPU
