Recorded Videos with no Extension? Can't Watch it!

[uquntu]

Hello, I have more than 25 recorded videos copied from my DVR hard disk drive and they do not have an "Extension name" or a "File type". Using WindowsXP, the details for one of the videos are:
Type of the File: File
Description(file name): 00000000
Size: 1,458,493 GB

I tried using VLC, KMplayer, K-lite Codecs but it doesn't work. I wonder if there is a special video player to make it work perhaps or adding an extension name to it?

I can upload the file and paste the link here if necessary but it would take some time.

Any help is appreciated,
Thanks

Open one with MediaInfo. It will tell you what the container is. Then rename the files with the right extension.

Thanks for replying

I just opened the file with Mediainfo but it doesn't show me any extra details, I checked all different view types Basic, Text, Sheet, HTML etc and they're all the same


This is what it shows in in sheet

CompleteName : I:\showbox drive F\SVOD\REC1515849334DIR\REC.TST\00000000
FileSize/String : 2.00 GiB

Oh, I missed that you copied these from a DVR. You're may be out of luck. They go to great lengths to lock content to the DVR. Maybe if you say what DVR you have someone will come up with something.

My DVR's original model name is "Multichoice DSTV PVR" made in South Africa, however, Showtime Network bought their hardware and changed its name to "SHOWBOX DVR 30015"

here are some pictures of both, they look exactly the same, even the remotes

The fact that MediaInfo doesn't show anything about the container indicates it is not any common A/V file format. Or that it is encrypted and you'll need to find some decryption software.
