burn

I've been really careful with my LG 55E6 for over a year & surprisingly video gaming hasn't affected it & I don't watch normal TV anyway. However, the native YouTube app has caused some very minor burn-in from the red logo at the top left which I didn't know existed until trying a magenta test...

I don't seem to be able to burn a DVD :( I've tried a few times and keep getting "Files waiting to be written to disk " I've tried imgburn and freeisoburner it's a it annoying I'm just trying to burn an Iso image HELP !
