I don't know if it's still the case but Comedy Central's video player was atrocious, the video wouldn't play unless it successfully played an ad but ads just straight up failed to load 30/40% of the time so you had to refresh, watch an ad to get to the video controls, scan back to your place, watch another ad because you crossed a 'commercial break' point, have that fail 10 minutes later, and repeat. The whole experience was awful and lead to me just scraping the site for the direct steam link and eventually just deciding that Jon Stewart wasn't worth it.
