We are having an issue encoding two interlaced inputs of differing resolutions on RDK 4.0 with the DM8168/9. If VIP0 has a 16-bit 480i30 input and VIP1 has a 16-bit 1080i30 input there are noticeable chroma errors in the encoder output:

However, if both inputs are switched to be 1080i30 the encoder output is OK:

The pass-through of the inputs looks OK so it appears that the error is happening in the encoder itself or is only in the bottom field of the capture. Any suggestions on what could be going wrong here?
Here is the description of our current usecase:
