Much improved! I had zero buffering screens, fairly good quality once it got going (about 1-2 seconds in) and could jump around the videos pretty much instantaneously.

 

With what I assume is the lowest quality the text is pretty much unreadable, but it's fine for the non-text videos. One step up from that is perfectly fine for all but the smaller text on his desktop.

 

With my crappy connection here at work, I'm very impressed that it starts playing as fast as it does and can manage decent quality.
