When I try to burn an ISO file via the right-click menu in gnome, it says I need to insert a blank cd to burn, although I have it already inside the recorder. I must open the cdrom folder via nautilus and then when I retry burning it get's recognized. I'm using supermount and I think it's because the cd isn't "mounted" until I open the nautilus window, then is mounted and the ISO can be burned.
i bet it's supermount.. in the 2.8 timeframe this should be fixed by using hal.
