I looked through the list and I think I noticed only one TAR match. Well, one is still enough. The site admin has his own views on that matter apparently. And I personally don't think they distribute it really. These tiny flash videos can't compare to DVD quality. I'd better buy a disc if I like the match than keep watching it online. I don't watch the matches at that site because it is impossible to fast forward the clip. I think they also used to have a system which split the file in multiple parts making it impossible to download and watch later. I see it as just one of the means to get familiar with a given match, nothing more.
Anyway, I just pointed the OP to a place to watch some 8-Ball.
