I use it.
You have to run your HH (both emailed and "saved to puter" versions will work) through this:

A couple notes:
- if you are using emailed HH, be sure your email is capable/set to receive 132ch display messages. yahoo does not. i had to change to a hotmail address for this reason. otherwise the HH will wrap and will not work in the converter/replayer - i forget which
- be on the lookout for player names containing spaces..."big fishy", etc. the converter cannot handle this - thus creating broke replay HH. when i see these, i have to copy/paste in notepad, "replacing all" to a non-space name.
Edit: shoot me a PM or "bluefeet66" AIM if you get stuck...we can walk through it
