I set the ring buffer size to 16 MB at run time by this option
  growisofs ...  -use-the-force-luke=bufsize:16M  ...
using a vanilla growisofs as it emerges from Andy's original
dvd+rw-tools-6.1 via command make.

dvd+rw-tools-6.1/growisofs.c  states that minimum size is 
1 MB and that only powers of 2 are permitted (i.e. 2M, 4M, ...).


For checking memory consumption of growisofs (on Linux) i would 
execute something like
  ps -eo pid,size,vsize,ucmd | fgrep growisofs
while growisofs is running. 


Have a nice day :)
