I've gone down the path of downloading videos off cycling torrents but having issues getting my equipment set up to play them easily.  Nothing beats popping a simple disc into the Blu-Ray/DVD player and using the remote to navigate.  No wifi issues, no airplay, no computer battery being low, now Windows 10 constant updates, etc. 

So, where is a good place to find older Tour de France, Giro and Vuelta DVD's?  I know World Cycling stopped releasing their DVD's a few years ago.

Ebay is a crap-shoot.
