I became aware of this problem only two days ago, after installing v.2.6 on an ancient laptop running Windows 8.1.
The symptom: the job queue never starts, the mini-window only says "PENDING".
The workaround:
disable the Wi-Fi adapter before using the encoder.
The solution: replace the original DtsJobQueue.exe with the fixed one. :-|

P.S.: I also discovered that the file dtshd.exe must be run in compatibility-mode (Windows 7 or earlier),
otherwise the splash screen will not be shown and the encoder's GUI will start minimized to the taskbar. :-/
