That is true, for most, but not for the g400 -- with DirectFB. I understand what you are saying about the unknown (rather undocumented) internal operations, but one of the DirectFB developers did some great work for the g400 and utilized it's tv-encoder as it is supposed to be, producing a perfectly timed, interlaced, overscanned output that looks _exactly_ like TV. No tearing, no interlacing artifacts -- none of that. > ModeLine "coryntsci" 14.3 720 760 824 910 480 484 492 525 interlace I will try that. But I have found that one modeline for one brand of video card just does not work with other video cards, so unless this is for a g400 specifically, I won't get my hopes up. > Which it can, but unless you are using production-quality hardware > with video genlocking, what you record will not be exactly synced with > what you get out. But you can. I have done so for years using another PVR application that could utilize DirectFB and g400 in tv-out mode. Encoding artifacts aside, it was TV-picture perfect. You could flip between tv and the signal going through the g400 and they were identical in smoothness and picture size. > Get thee to google for g400 tvout setup. Been there, done that. Nobody seems to want (or able to achieve) picture perfect output. There seems to be a lot of satisfaction with taking an ntsc signal and displaying it scaled to 800x600 on the framebuffer. That seems to be the state of the art with x11/framebuffer/matroxset. Sad thing is that it can look so much better. If anyone with a g400 is interested in seeing how good it can be, you need directfb and mplayer with the dfbmga video out driver. Use some source material that is suitable -- must be 480 lines, the more motion the better (to see the interlacing artifacts of X/framebuffer) but even just a ticker is sufficient to see it. Compare that with the mplayer on X/framebuffer with matroxset hacks. You will see what I mean. b.
