Where is NBC HD?

That's correct. Digitrans 7100 models are not able to decode SD 4:2:2 while the 7150's do. There are too many version of commercial receivers/decoders. One needs to know what is used for what.
Example: 7150ASI is a decoder that takes ASI for decoding only, no tuner.
7150T is a receiver without ASI out. 7150TA is a receiver with tuner with ASI.
Digitrans 71xx are pretty much similar to the GI/MOT 48xx.
Both Digitrans 71xx and GI/MOT 48xx can't take 8psk Trellis.
I am also using the EVS LVDS <---->ASI conversion. Got one on ebay for $25 from the seller you mentioned, real bargain.

Unfortunately, a lower model cannot be upgraded with a simple add-on card, as other broadcast gear can often be My Digitrans is the 7150T, has SDI but no ASI. I would have preferred ASI to SDI, since SDI decompresses the stream to full 270 megabit uncompressed--not the easiest thing to record to a hard drive. I do feel fortunate to own a Digitrans, so I'm not complaining

Thanks FTARock and Stefan for the information on the USB device, I might look into one of these...
