@jeannotmer you only need this patch if you are using moments or videostation AFAIK
@Tuonorosso that is a little bit weird because both versions of synocodectool seem to be patched - I am going to need a bit more details - which DSM Version, serial number format ((e.g. XXXXPDNXXXXXX for DS918+, XXXXODNXXXXXX for DS3617xs, XXXXLWNXXXXXX for 3615xs), the output of
sudo cat /var/log/messages
after you went online and lastly
sudo find / -name synocodectool
to see if there is a third synocodectool executable that overrides those settings...
