I have the exact same receiver; SR608.  I'm outputting DVI->HDMI to the receiver and the receiver is set to passthrough.  I have no overscan whatsoever.

When I first got the recievier, it did have overscan and I *think* this is what I did to fix it (it's been a couple of months).

On the receiver, under setup, Input/Output Assign - Monitor Out - HDMI should be set to "Through".  

my /etc/X11/Xorg.conf "screen" section is as follows (note, I'm running 1080P, not 720P):

Section "Screen"
    Identifier     "Screen0"
    Device         "Card0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "UseEvents" "True"
    Option         "ModeValidation" "NoVirtualSizeCheck"
        #Added based on http://www.mythtv.org/wiki/User_Manual:JudderFree
    Option         "FlatPanelProperties" "Scaling = Native"
    SubSection     "Display"
        Depth       24
        Modes      "1920x1080_60"
    EndSubSection
EndSection

Section "Extensions"
    Option         "Composite" "Disable"
EndSection

In my .nvidia-settings-rc  - I have overscan compensation set to 0
0/OverscanCompensation[DFP-0]=0

One other thing to note.  I do remember setting up the overscan properties, then changing the HDMI to "through" on the receiver.  One day, after a reboot i suspect, I noticed that the myth menus had black borders all around (too much overscan compensation obviously).  So, I believe that just changing the settings on the receiver were not enough, I think I had to restart X as well.  Just a thought.  Maybe just shutdown everything after making these changes and "reboot" the TV, receiver, and Mythbox.
