This has been driving me mad for about 4 months, having to resort to downloading tv to my laptop. I found the problem tonight! The KService would not run, this was because BBC and 4oD were conflicting!
Turns out the Channel 4oD service uses the same Kontiki software as the BBC iPlayer. I had uninstalled and reinstalled the iPlayer to no avail many times. This is what I did to fix it:
- From Windows Task Manager stop the KService and KHost processes.
- From Control Panel uninstall the BBC iPlayer and the 4oD player.
- Navigate to C:\Program Files\Kontiki and delete all the contents of the folder.
- Install the iPlayer.
- In task manager KService now runs, I had to start the iPlayer manually and tada now when I click download it works!
