Why MLB.tv, why?????

It's a double header and shockingly enough I'm able to watch Game 1 without a problem. When the game went into a rain delay, I tried to switch to the yanks game but it crashed my browser. This is frightening to me because I didn't log our before it crashed and may be locked out of my own account. Luckily, I'm okay and can log in again. So I watch the second game flawlessly until the 7th when I rewind because I miss what Dob and Jerry are laughing about. The browser crashes again. Now I'm really worried that I'll get locked out. Again I am spared and am able to start the 7th again. However at the end if that half inning, it freezes. The video just sticks on the commercial. I logout and reload the page. Nothing. I turn off nexdef. I paid extra for this but turn it off nonetheless. The video starts again and is... a......little. .... Chop...........py.....to.............say.................the................least. After much cursing, I turn down the video quality to one bar. Whew. It's much smoother. I can't read the score, but at least the video is smooth.
