Since this is apparently something several people would like to have,
I'll see to implement it in one of the next versions.

For a quick hack you could insert a line like

   system("myBeforeScript");

before the line 2131

   if (dvbApi->StartRecord(Recording.FileName(), Channels.GetByNumber(timer->channel)->ca, timer->priority))

in menu.c, and one like

   system("myAfterScript");

after the line 2176

   dvbApi->StopRecord();

(also in menu.c). Line numbers are based on VDR version 0.95.
