Does DT register work with CB Login module and the CB Registration process? I am creating 4 user memberships with CB Subs and after visitors become members they will be able to register for events-
DT Register does have integration with Community Builder. There is no direct connection to CB Subs though. In Joomla, it doesn't actually matter what module you use to login because you login to Joomla... regardless of the module. You don't login to CB, so that is all fine with DT Register as it will simply check if you are logged in or not.
You can also set access levels to DT Reg categories as Public, Registered or Special so the user will only see events of those categories based on their user level.
