there is a parameter to ivtv (ivtv_std) that defines the format setting it =2 configures it for PAL i believe. (I'm at work and this is from memory). That should help the framebuffer configuration once that's set properly.
ivtv-osd doesn't support mmap access any more. I am not sure whether -vo ivtv uses the frame buffer or the mpeg decoder. If it's the mpeg decoder then you need to make sure that the alpha setting for the OSD isn't getting in the way. You can use ivtvfbctl to turn it off.
