Haha, I remember getting into DT when the drummer audition videos first came out. I watched them multiple times and then started discovering the discography, it was a joy recognizing some of those snippets (it also compelled me to take up drumming). The same with Instrumedley. I had the Budokan DVD since 2006, but only really liked Instrumedley. Then I asked around on YouTube what some of the songs featured in it were and thus wound up listening to (and getting into) A Change of Seasons, Metropolis, The Dance of Eternity, Erotomania and even Liquid Tension Experiment.
