If you received the latest e-mail message from Twilight advising of a big sale they are having you can understand the studios reluctance to release old catalog titles on Blu-ray. Even though only 3000 copies were mastered Twilight still has inventory for Demetrius and the Gladiators, Desiree, the Rains of Ranchipur and many other titles released over a year ago. This is really really bad. If Twilight can't sell a measly 3000 copies of any movie whether it be considered good or bad the studios are going to withhold releasing catalog titles on Blu-ray.
Look what Fox is doing. They are releasing many old catalog titles on DVD-R in 4 x 3 letterbox or full screen. None of the recent titles I checked out included "Enhanced for 16 x 9 TV's" feature. I purchased Sodom and Gomorrah which is the full length version of 154 minutes presented in a cropped full view. Picture quality is decent for DVD. I also purchased King of the Khyber Rifles and that title is presented in 4x3 Letterbox.
I feel like I have taken a step 'Back to the Future" buying these Fox titles is like buying Laserdisc. I sold my Pioneer Laserdisc players and 100's of Laserdisc years ago.
For this reason I purchased a Region-Free Blu-ray player so I could buy some of the old catalog titles in Blu-ray. Titles like El Cid, Fall Roman Empire, Alexander Great, Runaway Train, and many more.
For the record I have purchased 12 titles from Twilight. I admit at $29.95 they are expensive so I do have to be selective. The bottom line is if there are titles in Region B you are interested in buy a region-Free player so you can purchase the titles. Don't wait for a Region A release because in all probability it won't happen.
