Keystone shorts on Spanish DVDs

The other day I just started to browse dvdgo.com, a Spanish DVD website, and noticed a series of Chaplin shorts on DVD, ranging from MAKING A LIVING up to THE BOND. Has anyone seen these? They are quite economically priced at about 10 Euros each, and contain at least 30 Keystone titles (plus TILLIE), so I'm very tempted to order a couple samples. It would, of course, also be interesting to see which versions of the Mutuals and Essanays they have. Anyone seen these discs?

I saw these too, and if I ever get any money I'll order some and find out. Somehow, given the price, my expectations aren't too high - but you never know. Please post if you learn anything about them. I'll do the same, of course.
