** Not your ordinary endless list - just what's number 1. Just the BEST.
There are some good pronunciation online sites, video or otherwise - but none beat the Univ. of Iowa's Phonetics.
I've been using and promoting it for almost 3 years and I'm always rewarded by how happy teachers are when they find the site. (how do I know they've found it through me online - well, I won't tell you all my secrets but if the link is the above, it is probably scooped from me. I'll avoid the discussion about "headsets" but enjoy the link just as it is...).

Students with distinct problems will find the site a wonder. It does two things that are SO crucial to the learner.
1. Shows a face slowly pronouncing.
2. Shows the articulation of the sounds in a clear fashion.
Pronunciation is one area where I do heartily believe in transfer - that we do have difficulties in pronouncing certain English phonemes based on our mother tongue. Students of many L1s will benefit practicing on Phonetiks.
I've will also mention that I've spent A LOT of time collecting the best videos and links for pronunciation on the internet.
Lots of great material in one handy place for teachers or students. I'm streaming daily pronunciation from youtube's API in HD format. Enjoy, great quality.
too, are all of EFL Classroom's pronunciation videos.
