Bad video - how can I fix it?

I have two tv spots sent by my client, a large chain of electronics stores. I
need to use the clips in a in house training DVD I am creating for them.

My first problem is that both videos have some corrupted frames. If I play them
in anything except VLC, the video goes very chunky for a few seconds several
times. For reasons that I don't understand, VLC plays both clips perfectly.

Is there some way I can then fix the problem? I noticed VLC does have some
export functionality but I can't figure out what settings to use.

Secondly, the clips are encoded as DIVX. Yes I know that DIVX is evil but this
is all they can get from their contacts with panasonic and samsung. They have
returned to them twice and have been told they can't send them anything else.

Convert the clips to DV AVI type 2

      Send them back to the client and tell him to supply you with editable
      material, not the crap he sent you. If they can't give you editable
material
      all bets are off and they have to double your budget and no guarantees
      it will work. Then try whatever is available to you, including
rerendering
      in AE.
