Compaq Presario 5170 - yaVDR
More info about the machine on the main page.
2011-01-27: I installed yaVDR 0.3.0 (from a cd made from the image yavdr-03.0a.iso) on the machine. I really wish I had found a faster machine, the installation took a few hours. And failed. xine-ui requires nvidia, which requires OpenGL, which requires a cpu with SSE (or SSE2?), which this machine doesn't have. Crap.
