a) that server shows it is running bukkit, thus not vanilla and this ticket is invalid.
b) your client is 1.7.5 which is no longer supported
You will need to contact the server owners for support, I would suggest verifying which version you need to be using to connect to each of them.
I have tested this in a vanilla server in 1.8-pre3 with the same result.
Crash report: http://pastebin.com/S14r5z1Y
Yesterday it managed to let me on to another server, but after windows updated, i got the same results in the video.
Just to make sure the server isn't modded, please force a crash by holding down F3+C or FN+F3+C for 10 seconds while in-game on the server and attach the crash report here.
