I had a general question about streaming videos online; in particular, on YouTube. What really is required to smoothly stream videos at 360p or 480p? Then for that HD goodness, what really allows a computer to smoothly stream 720p and 1080p?

I'm not too sure whether it's to do with the CPU (speed, # cores, cache size), GPU (chipset, VRAM, memory type) or even HDD (IDE vs SATA).

What contributes to the ability to stream regular videos and, furthermore, high-definition videos online?

Hi, I have a USB wifi card (D-Link DWA-125) on a Windows 7 x64 computer.

Create NSC-File for multicast streaming with Windows Media Streaming

as seen on Server Fault - Search for 'Server Fault'
For streaming multicast I need to create a NSC-file for the players - this file is pseudo-coded by Microsoft. Now I need to create this file for each proxy-publishingpoint. Is there any way to stream multicast without the NSC-file or can I create the NSC-file on another way? Thanks for any idea ;) >>> More

Facts: It is surprising and uncharacteristic that a wireless game streaming solution is the *first to hit the market when a 1000mbps+ Ethernet connection would accomplish the same feat with roughly 6x the available bandwidth. 150-300mbps WiFi is in no way superior to a 1000mbps+ LAN connection aside… >>> More
