@iamjinchi: its the corps, YouTube, etc. you nailed it on the dot. people dont realize things like the 5sec black screen isnt a bug but it doing its job. and the times that it makes the add unskippable is youtube trying to get you to turn the adblocker off, Not A Bug.

yes, it is a black screen for 5 seconds but it also prevents ads for the rest of the vid, turn it off and see for yourself!, i recommend turning it off for the initial ads, (to get around the times where the black screen bugs and stays for a long time, or the times where it just makes the ad unskippable and you have to refresh) then turning it back on after you skipped the initial ads. doing this prevents the 10 ads you get during the video, and the "in-video" ads are completely skipped, no black screen needed!
