Why is it that when a company releases a DVD of one of their titles that the picture is sometimes dirty? Not too noticibly dirty but a speck here and there... as if the film they transferred from was not clean. Why wouldn't the production company use a completely new film and if necessary take out the dirt using a computer before mass producing the final product? This especially affects some of the older titles (which I can understand to some degree) but also has been noticable to me on some new ones too. Anyone have any ideas?

Laziness...'nuff said. It is like some of the lame ass projectionists in the field. Enough to make you weep...

You would expect them to ultrasonically clean a print immediately before telecine, in which case (assuming the print wasn't beyond hope before it got cleaned), assuming the telecine was done properly, you shouldn't see any dirt.

Although prints are sometimes used to make the masters for video release, most today are made from a pre-print element, which offer much higher image quality. Sometimes an existing element is used, which may have some wear-and-tear from previous trips through printers or telecines. In most cases, digital "dust-busting" is used for cleaning up artifacts that were not removed by normal cleaning methods. But as with anything today, it's a cost/benefit judgement as to how much is done to make a perfect master.------------------

Typically, the major assett holders go to great pains to make the best possible element for transfer from original elements. Original negatives are often painstakingly cleaned frame by frame to remove dirt. But since many of these titles are older, much of the dirt may have been embedded over the years. Scratches and digs are identified and every effort is made to find replacement shots from other pre-print elements. Alas, in some cases there is nothing that can be done photochemically to eliminate some problems and the solution lies in the digital (and expensive) world. As John Pytlak has said, it often comes down to a cost factor.If you were able to see the condition of many negatives before any of this work is done, you would be amazement at the improvements.
