Matching HV20 to Panalook2 on XH-A1?
 

Anyone have suggestions? From what I have tried, the HV20 has way to much yellow in interior shots, so much that color correcting it that drastically simply distorts the picture.

Any suggestions on what to do?

Could that be a white balance issue? Try manually checking WB. Then see how it looks.

What do you edit with? For example on Premirer Pro sometimes such issues can be "fixed" by going into "Video Effects---Adjust---Levels or Color, whichever works best. It doesn't always work, but can sometimes help in a scrape. I think all your major NLE's offer something similar.
