I ran into a similar problem with one of my favorite westerns, 'The Wonderful Country'
It had never been released as a video or DVD.
So 'someone' recorded it on my Direct TV reciever, then 'someone' taped it onto a VCR, and then another 'someone' transferred it from VCR tape to DVD ...
By the way, my first Desert Shooter was in German format and would not play in my USA DVD
My second Desert Shooter DVD was in US format and works just fine ... so they do exist ... one just has to keep searching for it ...
BTW, Amazon has videos of this movie from $4.34 on up ... you could buy a really clean video, and have 'someone' Tranfer it to DVD for you ... then get an image of the marquee from the internet and make a cover for the jewel box for the DVD ... just a thought ....
Regret; it was released under three English titles; 1.)The Shooter, 2.) The Deadly Shooter, and 3.) The Desert Shooter ... don't know why ...
