I have a mac pro video subscription. Their videos are first rate and I think the site itself is easier to deal with, things like remembering where you were in a given video between visits and prompting for Play Next when you finish a chapter.
To me they do seem marginally more involved with more contemporary music styles but I've learned quite a bit through their site. +1
The Sonar video they have is, however, um, not so great...
Regards,
