Check here http://www.gnutellaforums.com/gettin...tml#post338511 & also check the 'Classic View' options for search results. Also remember to add columns to the window (for classic view only). Right-click top of heading bar of the columns & choose to show the column types you wish. This will give you more information. However you can right-click any search result & choose Get Info to get the specific details of the file whichever window view you are using for search results.

Personally I double click file size or bitrate columns or combination to help me in my choices. I do also show file type column which is not enabled by default.
