I always worry when I hear about stuff like this. Since my tracks were made with the official DTS encoder, there shouldn’t be anything wrong or incompatible about them, unless they’ve been extracted improperly. It must be an problem with the authoring software.

The only possible reason for it on my end could have been not selecting ‘embed timecode into file’ as an encoding option. I can’t remember whether I did that or not, and I don’t know if it actually makes any difference. That might explain the program’s inability to determine the true length of the file. Other programs aren’t having this issue, so it could well be something else entirely.
