So I was wondering if it would be possible to use the on board video decoder chips of the VIA EPIA boards like the VIA EPIA EX15000G http://www.via.com.tw/en/products/mainboards/motherboards.jsp?motherboa rd_id=450
This board mounts a CX700M2 chipset which features MPEG2/4 hardware decoding. It has DVI and Y/Pb/Pr video output as well as analog and SPDIF audio (coaxial and optical). So that's everything we need, isn't it.
for hdtv - no. I don't see the h.264 hardware decoding. mpeg4 is not h.264.
