I need your help!

Yesterday I capped a video in huffyuv and wave sound format with Fly2000TV (Fly Video 3000 cap. card). After the film ended I wanted to stop the recording but the program crashed (somehow the overlay continued to show the picture from the TV...).
The aftermath is that I have a large video that was not ended up (I suspect that it has something to do with the container, but I do not know much about video structures) and of course it's not readable.
I tried FourCC Changer to set it up with "HFYU" but this does not resolve my problem..

What software should I use to recover the frames and audio??

I tried
  • ASF-AVI-RM-WMV Repair
  • AVIFixed 2.0 beta1
but they didn't recognize the format and could not help me.

Thank you in advance!
