For starters it's not MAC, it's Mac. MAC is Media Access Control, which is a unique hardware level device identification address. Mac is short for the Macintosh computer. When you say MAC referring to a Macintosh it makes you look ignorant. Like back in 1997 when Apple allowed Microsoft to buy $5million in non controlling stock to sell back in 3yrs, and people would ask:
Uninformed consumer:
What kind of you computer do you have?
Mac user:
A Mac.
Uninformed consumer:
A MAC! Oh, I thought Windows bought MAC.
Now onto your question.

You might also want to look at your source footage. I had a hell of a time getting rid of interlacing on some Trigun footage that I got off a friends DVD. It turned out that the DVD was a aftermarket DVD that had been recorded or mastered interlaced and it was nearly imnpossible to Deinterlace it. Usually I don't have that much of a problem deinterlacing footage. One of the above options usually gets it for me. have you tried eliminating the alternate field instead of Odd try eliminating the even field and look at the results.
you might want to post some specifics.
