tuner tveeprom ivtv ivtv-fb then everything loads and reports properly in dmesg and I can read from /dev/video0 and output to /dev/video16 as expected, although now I have a separate issue.... The video quality is very bad in using the ivtvdev (0.10.6) x fb driver. It is pixelated and fuzzy, like I'm watching low bitrate streaming video with both myth and mplayer. The performance in the past has been excellent (indistinguishable from normal TV). CPU usage is below 5% (on a VIA C3, thats pretty good) while using the ivtvdev driver, the video is not choppy, just really bad quality, lots of blocks and artifacts showing up. Both mplayer and myth display great using the vesa driver on x and the built in unichrome video card (although CPU usage is through the roof as would be expected without acceleration of any kind) I've tried using the binary version of ivtvdev and compiled a version against xorg 6.8.2 with gcc 3.4.5, both act the same.
