There are a lot of fake channels solely for the purpose of luring viewers with ads, but here is how you can avoid any potential hiccups with pop-ups and ads.

--Do not download anything that is suggested.

--For every ad, there is an "X" button. It is typically in a corner or out of the way so it is hard to see. Sometimes ads try to fool you by giving you a fake "X" graphic which leads you to an ad. Do not be discouraged when this happens, the real "X" button is there somewhere.

--Multiple ads will pop and it takes a little bit to clear out each and every ad. Even then, pop-ups will occur as you clear the ads. Do not listen to any of these ads or pop-ups and clear them right away.

--This Robin Williams PBS special live stream will have recurring ads that pop up every once in a while. If this is the only way you can view the Robin Williams PBS special, do not be deterred and the live streaming will work once the ads disappear.

Be sure to check out the Robin Williams PBS special tonight at 9:00 p.m. EST.
