I just posted this 2d ago

There is a reply to that node with links to similar threads. And in one of those threads I wrote this: Could you post a representative sample of your input file, following the advice given here and here? In particular, show us a representative sample of your input using hexdump -C file or od -tx1c file, pasted here inside <code> tags.

If you don't show us your actual data, we will be left guessing, and you won't get any good answers. Please help us to help you. See also How do I post a question effectively?, I know what I mean. Why don't you?, and Short, Self-Contained, Correct Example.
