i'm assuming u meant MDR513H, i have this model and yes it works. you'll need to go to remotes.slingbox.com and create a 'custom remote'.
if you're planning to connect multiple sources, i'd recommend getting a 'digital switch' so you can change the audio source (slingbox solo only has one audio in).
i got the 'cables to go 28731' switch from amazon ~$40 and a new IR cable with 3 emitters (will probably also need a mono 3.5 mm to 2.5mm adapter to fit the IR cable to the slingbox (radio shack $5) .
my setup: cable box = component, MDR513H = composite, audio switch = s-video
