YouTube came with high quality a couple of weeks ago. YouTube have now three different qualities that people can choose what kind they want. They qualities they can choose between is: the normal quality that have a bit rate at 200 kbps, the mpeg4 that have a bit rate at 512 kbps and the HQ FLV that have a bit rate at 900 kbps.

When you are at YouTube just put &fmt=18 (MP4) or &fmt=6(HQ FLV) in the end of the URL to the video you are watching and hit enter. YouTube have made it like this because normally when you download a YouTube video you have to convert it in to MP4, AVI and so on, but now if you have put the MP4 code in the end of the video URL and you download it. You can put it directly in you IPod or IPhone.
