[VLC_help]

Like where you got the file, what does VLC say about the file (View -> Messages before opening)...

Does tools like GSpot or Mediainfo recognize the file correctly?

[eyalownz]

no they dont

[VLC_help]

Can you tell where you got those files? Seems that is some sort of proprietary format, which cannot be opened without special software installation.

I have some info on this file format. I am trying to reverse engineer it (just started today). It's supposed to be a h.264 format. I'll update you if I find out more.

I encountered it using a Hikvision PCI encoder card DS-4004HCI. They are used in CCTV security camera applications. Under the download section on the product page they have a download link for the media player plug-in (I couldn't follow the link. Here is a direct link).

You might want to contact that firm and ask source codes =) My guess is that without source codes (or huge sum of money) nothing is going to happen.
