I got one of these free from freeTVsignal. I see they're now out of stock.
My unit does not have the "full" EPG described in the online manual and shown in the screenshot in the first post in this thread (by Symbios). Menu -> Apps shows only "Simple Guide", and the "short" EPG does not have any menu (the only key it responds to is EXIT). The full EPG is also missing from my manual.
A number of other features seem to be disabled or reduced. There is less available with INFO. There is no AUTO option for aspect ratio
It does have one new feature: Menu->Setup->System Settings->Sound Output lets you choose Normal, Left, Right, or Mixed.
This unit has a SW Version of X1.00-09012008 -- apparently newer than the unit Symbios shows (X1.00-07302008). The HW and Loader versions are the same. (This comes from the "Factory Mode" screen - press MENU->1591).
Also, much of the menu text is almost unreadable on a 13" Sony screen (through the composite output). This is very different from the sharp text in Symbios's screenshots.
What do other folks see for versions and features?
Another thing I noticed is the Wiki page lists this unit as Energy Star compliant. But I don't see any mention on the package or in the manual, and it's not listed on Energy Star's current (1/5/09) list. An inexpensive meter (with resolution of 1 watt) shows usage of 5-6W, and 0W (less than .5W) in standby. It also has a 4hr auto shutoff. This seems like it would have met the requirements, had the manufacturer submitted it.
