well I was at my usaual forum, and someone built a DVB program that would display osd on HPlus type card.. well with little testing I see it worked with all sigma cards.. (congrates to emes30 for some original thinking)
but the interesting thing is with experimenting this approach, things could be applied universally.. to all dvd codec ( Emes30 is limited to one particular dshow filter that exposed the subpicture pin)
basically all you do is build pass through dvd navigator filter..
source- V->| passthrough | -> Video input codec pin
...........A-> | "DVD NAV' .| -> Audio indut codec pin
.................|_._._._._._._| -> subpicture pin
basicall all the pass through "dvd Nav " does if say that the out put is dvd compliant ( so the subpicture would be enabled on all codec) also if there is no souces pressent an backgroud image is displayed or if there is an actual dvd present. and if an source is pressent it will display switch to displaying the source..... but with investigating it seems that you should be able to build menus the same as any DVD menu found on any dvd.. and that it would display universaly..
I know SUB is unlikely to adopt this method . but I thought I mention it just In case it gave him some Ideas..
