Having a bit of a problem finding your HOWTO on that page.
I had a C3, good hardware. I used to use the Gentoo-based EpiOS distro, which was optimized for the C3s. But to get my board to play a DVD I had to recompile the video drivers and enable special acceleration functions, and even then playback was a little choppy. For people still using these C3 systems your howto might be very useful, however.
