Each fight night there are usually several posters looking for where to watch the big fight - been there myself. With a couple of days to go before this great fight, get in now and save yourself any last minute panic.
This site http://www.StreamTVnow is definitely showing the Tito v Winky fight. The fight is at 9pm New York time which is 2am UK time.
Its just $3 dollars for a month subscription and all you need to watch the streams is a DSL connection and WinAmp.
BTW I am just a member of this site and have nothing to gain from anyone joining up - just trying to help out as I have searched the 'net endlessly in the past looking for places to watch/download fights from and it's a major pain when you can't find anywhere.
Hope this helps. Cheers.
