Sean,
Some of the larger video's on YouTube, like the Kodak "How film is made" documentary, are split up in different sections on YouTube.
Maybe it would be a good idea to add a "links" section that allows you to add links to the other parts / sections of a video when adding it to the APUG video section. Of course, it is possible to do it in the Comments sections, but maybe a more clear option, displayed directly beneath the video when viewing it, might be in order.
Now, with only a limited amount of links to videos up, it is not a real problem, however, if we end up with hundreds of video links, it may become difficult to find the other sections of a video...
