Does this apply to dreambox as well? (dunno what vuDuo is, I assume it's another box?)
I have the exact same problem on my dm800hd, but the mentioned fix did not remedy the problem. Still the same.
The file ClockToText.* did not exist on my box, that's why I wonder if it's applicable on dreambox...
it did work for me on the VUDuo+ which is another form of STB. have you tried deleting the errant timers.xml first.
