I got the Mlg to stream as HD without having to click the stop button constantly, thus allowing me to watch it in fullscreen. This how I followed the soto's steps with some modifications.
Step 8 : Spam the IE stop button a few times.Step 1 : use Internet explorer to watch MLG. wait for the HD trial to expire.
step 2 : Hit the HD button
step 3 : spam the IE stop button.
step 4 : click the gears of war streaming tab
step 5 : File > Working Offline (Activate)
step 6 : File > Working Offline (De-activate)
Step 7 : Click world of warcraft stream
Step 9 : Get Netlimiter 2 Pro
Step 10: Set Explorer.exe to 1bit DL speed and then enable it by placing a check mark in the box beside it.
This will stop explorer from asking you if you want to go to another page. Now you can enjoy the stream free in HD fullscreen!
