problem with Mass Mailer and download videos : cron job?

Hello,
I have problem with my Mass Mailer Dolphin 7.0.6 and also download video does not work. If I send messages Mass Mailer is not starting. I think this problem just cron job?
I used cron job is 2 below:

cd /home/cpanelusername/public_html/periodic; /usr/local/bin/php -q cron.php
/usr/local/bin/php -q /home/cpanelusername/public_html/periodic/cron.php
What is the best solution?

your cron setting is really determined by where the php binary is located on the server. you should enquire of your host for the path to the php binary so that you are able to establish a connection to crond.

after looking more at  your inquiry here, im wondering if you are able to upload videos, then your cron wouldnt be the problem. as you state that you are having problems downloading. if you have a problem downloading a video, that could be directly indicative of a directory permissions issue.

The second one is correct for your environment.

thank you
