Preserving 4:1:1 colorspace from DV video source

[Perseverant]

Would 4:2:2 capture the extra 4:1:1 information without altering the video in a negative way, or would some undesirable conversion process happen?  I understand filesize might be a bit larger, but if 4:2:2 will retain the information I'd lose by going to 4:2:0, then I'd rather go with 4:2:2.
