Watching TV Online: CBS, ABC, Amazon's Unbox, and Youtube

As I recently made the transition from dial-up internet service to DSL, obviously, I have been watching a lot of TV online; what else is DSL for? I have used four different sites to view TV shows online. Each online TV viewing site provided me with different results. These results are chronicled below for your enjoyment and edification.

CBS.com (innertube)
I am not a huge fan of the show "Shark" but I enjoy James Woods and a recent episode feature another guest actor I like. I went to CBS.com on my lunch break one day, clicked my way into their easy-to access innertube page, where full episodes of "Shark" are available for viewing - along with episodes of the CSI's, Numb3ers, Jericho, and many other programs. I pressed play, flipped to another screen and watched a bit of the show. But then the buffering began. Then I could watch some. Then there was more buffering. Then I could watch some - but - then there was more buffering. Friends, there was quite a bit of buffering in my first attempt to watch TV online at cbs.com. However, I have to say, eventually, the next day, maybe, I tried again and the show didn't give me any problems. In short, while innertube caused me a moderate deal of frustration in my first run, it eventually was not a problem to load this "Shark" episode. Perhaps the speed of my dsl has something to do with it. Perhaps I just went online at a busy time. I'll leave that to someone more technically savvy to figure out. I could fast forward and rewind pretty easily once the buffering ended- though each segment of the show has a commercial break which one cannot fast-forward through (though, obviously, one can flip to another web page and turn down the volume...). The picture quality in the small box on the page is fine, but once I expanded to full screen, it was a little blurry. My fault or CBS's? I again leave that to the more technically savvy to figure out.

One cool thing, I bookmarked the page, and now, even though the episode isn't still listed on innertube, I can still watch it. Not that it's such a great episode.
