I think Dhinchaak and Dhinchaak 2 will b renamed Goldmines Movies and Hindi respectively. Goldmines Bhojpuri will b a new channel. Previously too we have seen broadcasters testing feed in similar way before replacing it with a current channel.
Having Goldmines branding is good as it has good recall value among people as well many people will discover Goldmines Telefilms thru this approach
