fix: stuttering due to unique commands in executable datasource

apparently, connecting unique sources can cause stutter in the video being played,
it was added as a way to avoid race conditions in callbacks
but since the interval is now 1 second i think this cab be safely removed
as the default command is very fast anyway

perhaps I will explore why that is happenign in the first place at some point
