Virginia if you have the file downloaded onto your machine try using VLC Media player (VLC). On the front of it there is an Extended Settings button and one of the tabs is called Synchronisation and you can adjust things in line again by putting an apporpriate value in the "Advance of audio over video" box (either + or -).

I downloaded one of the Transatlantic Sessions that I missed and it's oout of sync by 0.300 secs and VLC sorted it for me. I find it very odd watching out of sync video of music.
