I'm working on a HTPC/DVD system, and I'm planing on running Mythbuntu for the OS/DVR system. Does anyone know how AMD/ATI's drivers are for Linux? I'm thinking of running a SAPPHIRE 100292DDR3L Radeon HD 5450 1GB 64-bit DDR3 PCI Express 2.1 x16 HDCP Ready Low Profile Ready Video Card graphics card in it. And if there is decent driver support for Hauppauge WinTV Tuner cards on Linux? Going to get some like Hauppauge WinTV-HVR 1850 (updated version of 1800) MCE Kit 1128 PCI-Express x1 Interface down the road.
