L4D2 Dead Center Expert - 2 Players 2 Bots

Testing online multiplayer game after I had finally set up my new rig 2, 3 days back.
Hosted the game too to check out my new settings.
Volunteering guinea pig = my friend KeNa who wanted to play L4D2. LoL.
Have a very good connection at home but had a old paper computer and a 5 year old wireless G series adapter.

Game settings were maxed out.

Mainboard : MSI P67A-GD55 (MS-7681)
Chipset : Intel Sandy Bridge
Processor : Intel Core i5 2500K @ 3300MHz
Physical Memory : 8192MB (2 x 4096 DDR3-SDRAM )
Video Card : NVIDIA GeForce GTX 460
Operating System : Windows 7 Home Premium Home Edition Media Center 6.01.7600 (64-bit)
CPU Casing: Cooler Master HAF912
Wireless Adapter: TP-Link 300MBPS High Gain Wireless N USB Adapter
PSU: SeaSonic 620W True Power

Unfortunately, my Mum and Dad were streaming videos separately which results in KeNa having mad laggness especially during the finale so I could not test out the extend of how good my new computer can function yet.

And I have no idea why after I uploaded to YouTube another extra 4 was added to my video height which resulted in the green bar below again -_-
My rendered video was 1280x720 became 1280x724 on YouTube.
