That's the problem; we were given this disc by the police.
One problem in our industry is everybody works as autonomous units (think different city, different software / leadership / way things work). We get a lot of discovery (usable evidence in court) in proprietary audio and video formats that then need to be converted for use in Court - as the courthouse only excepts Video that can be played in a standard DVD player or audio that can be played in a standard CD player.
I have at least a dozen different proprietary video players from bus surveillance systems to jail call audio all in different formats - or better yet, the audio will be in .wav format but has a stupid proprietary wrapper around it so it can only be played in that software. Often times, these players aren't usable in Windows 7 either, which makes things more difficult with the 2014 end date for Support for XP from Microsoft.
Also, you have major egos involved between the senior leadership of different law segments who don't always play nice in the sandbox, thus standardization is very difficult to achieve.
