First I'd like to thank TPeterson, Kei, jldet5, balazer, and whoever else I forgot, who helped me with the timing issues I was having.
To summarize, there are 2 utilities which essentially do the function of PowerStrip for MyHD. They cannot do everything PowerStrip can, but much of what you'd use PowerStrip for can be done. In particular centering the picture and adjusting for overscan. The utilities are somewhere in the big MDP-130 thread. The documentation is rudimentary but enough to get you started. I added some notes and links to the original posts where you can get the utilities. Hopefully this will make it easier for other folks to use the utilities.
The image from MyHD MDP-130 using DVI daughtercard to HDMI/DVI ports of my Sharp LC-45GX6U (at 1080i and 720p) was off center. Specifically the picture shifted to the right 42 pixels and shifted down 5 pixels. Sharp has decent picture adjustments and I was able to center the picture using the displays controls (and save the values), but it is always nicer if the source device outputs something already centered, especially if the display's input will be shared with multiple devices.
In the end, I was able to get the 1080i image perfectly centered with 1:1 dot mapping. Sharp has a "Dot by Dot" view mode that bypasses the scaler and does 1:1 dot mapping. Here are the settings I used for the Sharp 45". You may not like my overscan values as you will see junk on the edges of some network broadcasts, but I've grown used to seeing exactly what the networks broadcast so it doesn't bother me. This particular display has native res 1920x1080 so I try to get rid of scaling as much as possible through the whole pathway, especially for 1080i content.
Originally I went down this path because the 1080i output from MDP-130 DVI would not display properly on my Sony Bravia KLV-S32A10 LCD TV. The picture would display, but the top part of the picture would experience tearing. Unfortunately I ended up returning that TV before I was able to use syncsetup to see of that problem could be fixed.Please be very careful when you use these utilities as you can potentially damage your screen, basically the same warnings as PowerStrip.
These were my Sharp LC-45GX6U settings using the DVI-I port configured for "AV Digital" with 1080i input from MyHD MDP-130 over DVI daughtercard.

These are my notes for scansetup and syncsetup usage.

UnderScan 6 6 0 0
OverScan - how much of the incoming picture (from broadcaster) to cut out
remaining picture will be stretched to fit the output window
useful for getting rid of broadcast junk at the edges of picture, especially top/bottom edges
UnderScan - how much of the outgoing picture frame is not visible due to display's overscan
basically this treats part of the outgoing picture frame as not usable.
The picture content from MyHD is shrunk to fit into the reduced usable picture frame.
This is useful if your display overscans the picture (ie expands the picture so about
5-7% of each edge is off screen)
If you are seeing junk at the edges of the picture, use OverScan to get rid of it
If your picture is off the screen because your display is overscanning, use UnderScan
to have MyHD shrink the picture to account for the overscan.

Vertical - negative Offset values shift picture up
The documentation from MIT implies this utility might work for the DVI output only
. However there is some uncertainty on this and it may work with DVI and VGA out. I have only tested DVI and confirmed it works.
According to their instructions you must disable
Config Panel->VGA->Enable DVI Output
for this utility to take effect. I just followed their instructions and did not experiment further.
Prior to using syncsetup, you should run the MyHD player once and exit.
If you have not run MyHD player since booting, the Front/Back porch will
not have been loaded and the syncoffset program will read them as zero.
It doesn't affect the function of syncoffset, but could be confusing to
I suggest when running syncsetup, do not exit until your session is
complete. Change some values, press save, start MyHD player, see how
it looks, exit player, change some more values, press save
, start MyHD
player, etc. The reason I don't suggest exiting syncsetup is because
when it restarts, the front/porch values will reflect your previous
Offset change, but the Offset field will be reset to zero. This can be
confusing to end user.
If you totally mess everything up, you can always delete the appropriate
registry values and the player will load the defaults
