Hi again,
as an exception, I will answer my own posting because I found the reason for my problems. If one of the moderators would be so kind, he might move all postings related to this subject to a new thread, perhaps in the audio encoding forum.
First of all, reripping the DTS audio CDs was not the solution, because the ripped dtswav files were okay. The problem was caused by the programs which are used to convert dtswav files to dts files. I tried three different programs, that's wav2dts, besplit and DTSParser, and for some reason, all of them set the frame size in newly produced dts files to 3585 byte instead of 3584 byte by mistake. I found that by comparing the DTS headers of one of the defective files to another DTS file, which are working fine. The informations on that website were helpful for me to point out the error:

Is it possible that the authors of all three programs did not notice that the relevant header field must contain the frame size - 1 ?
