Well, see, that's the thing, and trust me, I've been right there before (lol). You did the right thing by re-saving, even though you still ended up with Odd. Just do it again, and if necissary, again and again, until you get a good consistent frame that fits your needs. I've had to re-save more than ten times before.
It's just like a coinflip. Sometimes you get a bunch of tails in a row, but eventually you'll get heads. :D
