Is there a program that can show you detailed information about video files like EncSpot can for audio files?
In particular, something that can list all your video files and show what type of codec is used (MPEG1/2/4, DivX, XviD etc), as well as resolution, bitrate for video/audio etc etc.
The 2 I use are GSpot ( http://www.headbands.com/gspot/ ) and BitRate Viewer ( http://www.tecoltd.com/bitratev.htm )
Also if your movies are associated with Windows Media Player, then a simple right click on the file, go to Properties, then Summary will give you a LOT of information and quickly.
