It appears that Optiumum Home Entertainment will re-release Ken Russell's 'Valentino' for DVD on September 1, 2008.
This is a region2 disc. You can also check out the link at Amazon here.

I'm not sure if this DVD is in the correct aspect ratio (the lower price suggests otherwise).
Either way, the title's been hard to find for a while now. Here's hoping for The Music Lovers, Savage Messiah, The Devils, et al.
