Which one specifically doesn't work for you? I just tried "Good and Bad Bishops" and "Into the Fire" from 2010 and they work OK for me (I just watched the first little bit though).
Resolved; Video Lectures Inaccessible

Good and Bad Bishops; Averbakh v. Furman,1960 and Good and Bad Bishops; Ivanchuk v Anand, 1992. Hopefully, it is just my computer and not the server, which seems plausible. Just checked again and they still won't run for me... this is odd
I was trying to watch GM Khachiyan's video lectures from early 2010 but they won't work. Is there any way to remedy this?
