Well finally got on about 3 hours ago, watching through the PS4 app (in the UK, pretty awesome how all you need is a US address to sign up then a US PSN account). With so much stuff to access right away it took me a long time of browsing before settling on Halloween Havoc 1996, not really sure why. It was pretty jerky to begin with, just about got through the awesome Malenko/Mysterio opener (I forgot just how fantastic the WCW Cruisers were) alas it was then it crashed on me. Got back in and decided to relive the Raw from 1998 on there (the Austin on a Zamboni episode) the stream was a lot better, had no problems with it, going to check out Judgement Day 1998 tomorrow as that's the PPV that Raw is hyping.
So far seems like a good service that has the potential to be fantastic, especially for people like myself, I was a wrestling nut from about 1990, tapered of in 2006 and hardly watch now. If they can get enough Raw's and Nitro's on there so you could effectively go through a whole year of that companies TV and PPV's I will be ecstatic. I know they're going to have they're own Monday Night Wars series, but I also want the option to watch the whole episodes of those shows. See the random Meng vs Glacier type bouts are what its all about!
