Haven't heard diddly-poo about any of those titles and would LOVE to get my hands on all three. I'm sure these titles can't be too far off because they are Eastwood films and if The Beguiled can get a DVD release...
Also, you left off A Perfect World-another very much sought after Eastwood film.
You can add to that list Coogan's Bluff, Where Eagles Dare, and Two Mules For Sister Sara. Warner controls most of these "MIA" titles and they are not the fastest at releasing back catalog titles. Every Which Way But Loose and Any Which Way You Can are only now coming out and these were some of Eastwood's most successful films (financially).
A Perfect World was released long ago, right after the DVD format was introduced. It may be out of print now, or just hard to find.
