If you download video frequently you probably run into the problem of not being able to play back the downloaded file occasionally. Maybe the audio works but not the video, or the opposite, or maybe you get nothing. When that happens it’s time for forensics, and if you’re like me it also frequently means, ‘ehh, who has the time,’ and passing on watching the video. I noticed another tool you can use for analysis of these files today, mediainfo, a free, open source, somewhat cross platform (windows and linux) video forensics tool. Check it out if this is something you run into. It’s also useful if you frequently do transcoding so you can play files on your ipod, psp, gp2x or whatever.
