Where to view recent full professional matches with commentary?

I literally can't find anything. I have no idea where to look. On the dota client, I can only find stream from as recently as... TI3. I can't see any other competitions showing up. I don't see anything on youtube either that ALSO is a full match. NoobfromUA has matches, but they jump around.

So my question is, where do I find streams with commentary? The reason is because ideally they'll go into the reason players are making certain decisions.
