Experienced Sopcast Users

Can a couple of you guys help me and some of the other newbies out by giving a bit of guidance of how to use sopcast. Maybe I'm a retard and the only one struggling trying to understand how to use it, but even in that case some guidance would be appreciated.

Some of my questions right now:

What is the easiest way to figure out the channel of the event you're trying to watch?

Is there any way other than viewing a channel to see what its quality will be?

Any advice or tips y'all have is appreciated, I thought it would make sense to have a thread that has all the info formation in one place, since it is usually brought up randomly in other topics and lost in the other conversations.
