In my opinion, the Spinerval DVDs tend to be a little more intense, and less focused on cycling technique, etc. They seem more work-out oriented. The CTS DVDs have more cycling-specific stuff. The downside of the CTS DVDs is Carmichael's relentless salesmanship. He's always pitching CTS coaching and Powerbars. It strikes me as ludicrous (sp?) when, before the last 10 minute interval of a +/- 50 minute workout he tells everyone it's time to eat your Powerbars. I mean, it's not even an hour workout, and that Powerbar really isn't going to get into your system soon enough to help get you through the last 10 minutes of the workout.
By the way, there was a thread last winter or spring asking people to describe the contents of various workout DVDs. The thread didn't get very far, but you might find some useful info there. Sorry, I don't remember any specifics to search for.
Re/your question on whether the DVDs are worth buying, I think so. The DVDs make the trainer time go faster than just listening to music, and like riding with others can help encourage intensity. Also, particularly in the case of the CTS DVDs, they give you a demonstration to augment the text descriptions from training books, etc. The downside is that many of the workouts are too intense (IMO) for much of the season (late fall, winter) when you'd be using them the most.
