Basically you can’t watch any video from that site without waiting 90 seconds… even if trusted Ads are enabled.

I clicked on a video on that site and it started playing it almost immediately. Is there a certain video I should check?

Some of them appear to work fine others, don’t.
for example makes you wait.

I think that’s likely normal. Hulu does the same thing for me when AdBlockPlus blocks the ad it was going to play. I don’t know that there’s a way around it, but I suppose it’s worth asking about.
