Hello, the primary source of information for linux on epia is there: http://www.epiawiki.org/wiki/tiki-index.php There are some howtos, some ebuilds, but they rapidly get out of date... They are posted by people with specific problems, which may not be exactly yours. For example kernel ebuilds do not include the lirc patch, which you will need to build a pvr. They contain the standard drm patches which are too old for use with the newest Xorg patches for hw mpeg2, etc... To get my current kernel, I had to manually patch the vanilla kernel with the cko patchset (for reiser4, lirc, vesafb-tng), add the viafb patch (native framebuffer), the vt1211 patch (for lm_sensors), CVS drm... To build Xorg with HW mpeg2 accel, you need to break the emerge into several ebuild steps, applying patches to the unpacked tree before completing the process... Now xine and mplayer natively support the cle266 hw mpeg2 decoding, as does mythtv, so you just need to emerge them with the correct USE flags... I do not do cross compiling, as everything works OK natively even if not very fast. > > Also how well is the Mpeg2 HW working?

Quality is acceptable but not excellent. I heard in forums that you can get much better quality with a hauppauge PVR350 (which unlike the PVR250, does decoding as well as encoding)... and it is supported by MythTV. WRT transcoding, I have no idea as I never tried it... Sorry! Just keep in mind that on epia motherboards (mini-itx) you only have one pci slot, so decide carefully what peripheral you'll plug into it! If you need more information, just ask me. I have spent much time into this and I am willing to share my experience. I'm just too lazy to write all this down in a howto... Aurelien -- gentoo-user@gentoo.org mailing list
