I attempted to play the CD on a PC in our office.
It opened up the file using Windows Media player but it wouldn't play.
An error message came up saying "Windows encountered a problem while playing the file".
The PC's in our office are all used for admin purposes and are not of any high spec however.
We don't have a DVD player in the office but I doubt it would play anyway.
I have a similar situation. I'm assuming you never found a solution to this.
The CD I received actually had software on it ( I assume what came with the DVR) called DVR Player.
Says it's from Wal-Mart.
However I still cannot get it to read the avi file and there is nothing else the software can open on the CD.
VLC has the exact same message.
I can't get any converter to recognize it either or anything to even play it.
Download the "Evidence Reviewer" and it should work on your work PC. I am not certain about Macs yet. The VLC player, Windows Media, etc., nothing worked until my husband suggest I download this. It is free, but it takes a few steps. But at least I can finally review surveillance footage!!!
Hope this helps!
