i always liked the "Great Ideas of Philosophy" series by Daniel Robinson, for the Teaching Company (now the Great Courses). it's available to purchase from the great courses website or from Wondrium's very good subscription lectures streaming service. Lecture sets from these two companies are generally of the highest standard.

If you would like to sample it before patronising either of those two businesses, it seems to have been uploaded on youtube.
