There is enough variance in digital processing implementations that I can't comment based on that info as to whether your system generated a good pattern or not.
The best advice I can think of to confirm things is to connect another 4:3 display (such as a modern CRT set) that is known NOT to have excessive over scan to both signal sources in the same manner as your Tech-Master and see if there is a black bar wrapped around that test pattern, or if the DTV picture is excessively zoomed (I suspect one of those is occurring).
With changing aspect ratios and poorly standardized means of dealing with it flooding consumer and broadcast markets alike, there is good argument to keep a VCR or pre-2000 test pattern generator on hand...So you know you have a signal source that will always give you an accurate measure of over-scan...
Too many modern signal sources are capable of distorting things and giving a misleading signal.
