Can't Burn DVDs After Kernel update

[rey1321]

Hi guys! I had been using K9copy for along time and never had any problem, but now after a kernel update(through automatic update), I can't burn DVDs, insted i get the following error:



I: -input-charset not specified, using utf-8 (detected in locale settings)
wodim; operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK limits.
wodim; WARNING: Data may not fit on current disk.
wodim; Notice more recorders cannot write CD's >= 90 minutes

wodim; Notice overburning active> trying to write more than the official disk capacity.

Wodim;

Please any advise, I love K9copy and want to keep it
Thanks
