The DTE-7100 does only 4:2:0 DVB and DCII, the DTE-7150 adds 4:2:2 capability. Both units look identical. The GI/Motorola equivalent of the Digitrans 7150 is the DSR-4800, but I am not aware of an equivalent of the 7100 (although there probably is one, perhaps a subset of the 4800 series). Some versions of the 7100 that have been on E-Bay recently do have an ASI out, which allows them to be connected to a 4:2:2 decoder such as the one discussed in this thread.
