It worked with an NEC DLP projector, although it was intermittent, and as I mentioned, not with the Barco DP100. Those are the only two I have experience with.
The three pattern generators with no 1080p23.98 problem going into the Barco DP100 are S&W HD Source, Omnitek, and a high end Japanese brand. Since the main format used by the Barco DP100 is 1080p23.98 in digital cinema, I am sure that there is nothing wrong at that end.
I discussed this with Teranex four years ago and they told me that there was nothing wrong with their 1080p23.98 output. Since the Teranex 1080sf23.98 output worked, and in this case the end result is identical, I did not pursue it further.
