vision format

Hi all
My old HD with many ETV recordings from 2007-08 crashed few years ago and I hadn´t a backup.
A friend of mine helped me to reopen it and I got a long row of files, unfortunately cut I small or 64MB pieces and totally mixed up (There were 240 recordings but I got about 800 files).
I have tried to play these files and I have tried all sorts of common programs (VCL, Media Player Classic, Real Player, Pot Player and many others).
The result is unusable. I can play the files (by using different players) but I can hardly recognize the content. I have been told, that the explanation is, that the HD use a non standard file system called “vision format” What do I do. Can anybody help me?
Stig

Thank you for answers and advices
I have tried to rename the files types without any difference
I´ll will try all the other proposals and it will take some times.
I´ll will return with the result
Thanks again
Stig

From what you say I think that you should try to get the data again with a different tool.

I remember that when my HDD was damaged I've tried dozens of programs trying to recover any data.
The only one that worked for me was "MiniTool Partition Recovery"

Many common players could not even open a file, and when I found one, which could, and looked at the result (video) and heard the sound, both parts was horrible, and not synchronous. I will not upload such rubbish.

What happens if you change file extention/type on a copy of file to .mpg?. Then try opening with your player.

if still no-go, (now it gets technical), download dgmpgdec from here :-[Versteckter Link - Registrierung notwendig]

Open file with dgmpgdec and save project and demux video to save video/audio to elementary steams

Then remux video/audio with muxman found here under vob tools [Versteckter Link - Registrierung notwendig]

Good luck

Excuse for my late reaction, - I´ve been away some days.
Thank you to Shirtful land ZXCCXZ30 for your replies.
Some more facts.
The damaged HD has been open with “Ontrack Easy Recovery, - Home” and the result was 16 directories.
The smallest directory has two files, one of them (140 MB) with 5 clips and the other file (599 MB) also with 5 clips.
The biggest directory has 445 files. The smallest file, = 0.78 MB and one clip. The largest file = 2.0 GB and 29 clips. All together 16 directories, = 599 files and about 1600 clips.
I have had 250-300 recordings on my HD. It means, that these recordings are split up in smaller pieces, - and these small pieces are placed in different directories / files and I cannot find the key to understand the system. I hope you understand my explanation Mr. ZXCCXZ30

I think you are quite right Mr. Shirtfull, that I have to find something, which can handle that spooky vision-format. Can somebody give me that hint?
The HD (Fujitsu MHV2080AT/80GB) was built into a SAT box (Digiality CX-C1 422 TS) and both were damages under a thunderstorm back in 2009 and the satbox are now thrown away
By the way, I am not an IT expert, just a common user, and English isn´t my language, anyhow I hope you understand this note

I don't understand that part.
Maybe you could upload a sample of problematic recordings?

Is the HD in a Set top box/recorder as “vision format” is not a recognized hd format but a format/catalogue used by some manufacturers similar to dvd on HD.

Check support site for device to see if format/catalogue can be repaired
