We had attempted to develop the 422 codec approach with the current ALI chipsets last year and understand the issues involved. We were unable to provide reliable decoding all 422 transmissions. When the function is not native, the CPU demand is too great. This is why we abandoned 422 quest on the lower end STB.
422 process can be added to most receivers with a daughter board, but then the hardware solution costs more than the chipsets that can do 422p.
