Take a look at some of the talks by Ajahn Jayasaro on DhammaTube:
They are short, but very useful talks — just straight Dhamma teaching.
You will also find a series of his talks on the Biography of Ajahn Chah. I know Ajahn Jayasaro from my stay at Wat Pah Nanachat, when Ajahn Pasanno was the abbot. Ajahn Jayasaro became the abbot there for a period later.
This is the first of A Series of Talks on Meditation
