I agree with you. Real instruction is the only way to go. Videos add a little bit, but they are like salt and pepper. The real dish comes from a live teacher.
On a side note, Mr Bussey gets a lot of bashing because he left the Bujinkan. I have no problem with him and am a fan of his videos.

If you characterize his videos as just self defense videos then yes there is some worth. However, truthfully he characterized his videos as Ninjutsu which he clearly did not have enough authentic expertise in. This is and will always be the source of issues with Mr. Bussey's Ninjutsu videos. Now he has moved on and is teaching Bussey Combatives: http://www.robertbussey.com/ ! Personally I hope that everything goes well for him and that he finds his niche.
