Giant Bomb videos, since some post-CBS migration (I think the player changed a few months ago) have been hideously slow. Where possible, I just watch the lower quality YouTube videos at this point, sacrificing quality to simply watch the damn things at all.
Noticed the same thing. The video on the site got hella slow when they moved to CBSi. I wonder if they went from Amazon to some CDN owned by CBS. Either way, HD video (and sometimes "high" and "low" res video) is freaking slow on my 20mb/s connection. I can stream HD on Netflix and Hulu just fine. When I occasionally try to download video from GB, I only get a download speed of like 170kb/s, futhering my theory that something is wrong with whatever content delivery system their using.
