DVD 90 minutes (2004) All-In Productions.  The first 2/3 of this video is strictly for beginners, but later on there is a very good section on tells.  Lederer explains several reliable tells and the camera illustrates them clearly.  The introductory portion explains the rules of no-limit hold'em and they play an illustrative hand face-up.  Basic concepts are included like the importance of good starting hands, outs and odds, domination, and position.  Lederer also describes how to set up a home no-limit tournament.  See back of box, Secrets of No-Limit Hold'em, Howard Lederer .
