Micomsoft Xselect-D4 - LMH1251 Chip? / Rec.601 Colorimetry?

[M3Patterns]

Does anyone know for certain if the Xselect-D4 uses the LMH1251 chip?

If it does not, does the Xselect-D4 properly handles 480p / SD signals correctly with respect to Rec.601 color? (That means it would be using the following for luma when handling those signals: Y = 0.299R + 0.587G + 0.114B.)

It looks like some component to VGA adapters simplify things and apply rec.709 color decoding to everything, which is incorrect for 480p / SD signals. (Rec. 709 luma is Y = 0.2126R + 0.7152G + 0.0722B)
