Hi I don't know if this is useful. I could not compile many plugins with 1.5.1 until I made the following change in ./include/vdr/osdbase.h, in "class cOsdObject" I moved "bool needsFastResponse;" from private to public scope. Then most of my plugin probs went away. Don't have the faintest idea what I am doing so you can ignore/use if you wish. cheers Anthony Kelly
