And I think "good enough source quality" is the most important key. For the past two weeks, I've been watching live
streaming of the U.S. Open in New York, both on the Open's web site and ESPN3 (or whatever it's been renamed to now),
and found the stream from the Open's site to be much better in quality with less pauses, break-ups, and complete
stoppages. I'm sure there were a lot less people on its site than on ESPN at any given time, so that may explain part of
it.
One of the PC's I was using has an AMD Athlon 64 x2 4800+ (2.5GHz) CPU, 4GB RAM, and an Nvidia GeForce GT 240 w/1GB VRAM
running WinXP Home 32-bit. The other is my notebook with and Intel T8300 Core2 Duo 2.4GHz CPU, 4GB RAM and a dedicated
ATI Mobility Radeon HD 2600 w/500MB VRAM running Win7 Home Premium 32-bit. Both of them had equal quality video,
although the picture was a little sharper on the 15.5" notebook screen than on my 22" widescreen Acer LCD. But, I have
the Acer connected through the VGA port and the notebook is HD, and pictures are generally sharper on smaller screens
than on larger ones (discounting the HD part).
