Good boxing instructional videos for someone who can't physically train

I have been a fight fan since I was a kid, but only got to train for a brief time before an unrelated set of injuries (back, labrum, pec tendon) put a permanent end to that, and a lot of other things. Still, I'm just as interested now as I ever was in the mechanics and strategy of boxing. I compulsively watch and re-watch videos of known fighters training, all of the Duran and Chocolatito breakdowns, etc. Read Dempsey's book the other day as well. But all of this is very patchwork, very non-linear, and difficult to piece together when you haven't even seen a heavybag in 15 years.

Can anyone recommend a good video series that teaches technique, form and strategy beyond what a 5-minute youtube tutorial is going to show me? I'm not likely to see the inside of a gym again, but everything I do learn gives me a greater appreciation for the fights and fighters I watch. A 95 MPH fastball is a lot more impressive once you've realized that everyone else can only throw 85, and why.

Since I'm not some highschool kid looking to beat up his bully, I was hoping some of you could recommend some real boxing instructional videos.
