5000W converter must be an expencive device for shure but maynot be enough depending on the power/ch of your AVR.
check with manufacturer(s) if you can eliminate few of your components by simply switching to 220V operation. most receivers do have that to begin with.
as to dvd-player don't even bother -- it'll shurely work.
