Ok, I got confused, but why do you use VideoAspect * OsdHeight instead of OsdWidth? Most probably the problem is caused because the dxr3 plugin doesn't implement the GetOsdSize and GetVideoSize method, but the xine plugin does implement them. Anyway, since the cDevice::GetVideoSize returns 0 if not overridden, I put a check VideoWidth == 0 in SetOsdData. > Can you provide me with some sample recording that demonstrates the > problem you are seeing? I think you can check by yourself: I tested with the bbc channels at 28.2E.
