group management with vdr and latest ppa release

Hi there,

maybe someone can point me to the right direction.

I am currently using XBMC (latest ppa release) with xvdr and latest xbmc plugin (self compiled from actual git).

In the LiveTV Section there is a possibility to add own channel groups for TV and sort in stations which I did.
The whole thing works until the next restart of XBMC, after that the new added group is empty.

Can someone tell me if this is caused by a setting?

If not, is there a way to save the own groups so they're alive after a XBMC restart?

Thanks for your answers.

Dan
