HD videos thru Youtube on WiFi still grainy

[Tricon7]

Where I work they have a WiFi connection, and I just started using it for my iPhone 4. I've viewed certain videos on Youtube that are in HD, and on my home computer they look great. But when I went to view the same video on my iPhone Youtube app, it looked wretched. Grainy *at best*. And it was recorded in HD no less. Is there a reason why this may be happening?

It's purely related to the quality of the video, nothing to do with your iPhone, with the YouTube app, or with the wifi Internet connection. YouTube buffer video through the size of the video, so if your wifi connection is not good, it will take time buffering the video but at the end the quality of the video will still be the what it originally is.
