[vdr] Softdevice-logs getting flodded

My logs are getting flodded with this:

Nov 13 19:13:05 vdr vdr[6916]: [VideoOut]: aspect changed (0 -> 0 ; 1.333333 -> 1.333333) Nov 13 19:13:05 vdr vdr[6916]: [VideoOut]: aspect changed (0 -> 0 ; 1.333333 -> 1.333333) Nov 13 19:13:05 vdr vdr[6916]: [VideoOut]: aspect changed (0 -> 0 ; 1.333333 -> 1.333333) Nov 13 19:13:05 vdr vdr[6916]: [VideoOut]: aspect changed (0 -> 0 ; 1.333333 -> 1.333333) Nov 13 19:13:05 vdr vdr[6916]: [VideoOut]: aspect changed (0 -> 0 ; 1.333333 -> 1.333333) Nov 13 19:13:05 vdr vdr[6916]: [VideoOut]: aspect changed (0 -> 0 ; 1.333333 -> 1.333333)

several times a second, non-stop

Any ideas?
