Auto TP, Auto Roll, On or OFF?

Can someone help.
Is it best to leave them on or off?
Thank you

auto tp =on
auto roll= off

Auto roll can't work anymore--that worked by decrypting CA EMM packets which you can't do.
Auto TP reads the packets (PAT) that tell the box what channels are on a TP--that is not something that is encrypted in the DVB-S type standards.

Thanks, Gentlemen
