I can't access Twitch chat rooms through IRC.
Title: Bruv
I don't feel confident about that, but I understand there are tools available for joining Twitch chat conversations.
I also use mIRC.

Yes, you're right. I rely on Chatty since it includes Livestreamer. Livestreamer lets you view Twitch smoothly in MPC or VLC with minimal CPU demand.
