youtube is converting all it's video into higher quality and if your broadband speed is fast enough then youtube will detect this and automatically play the video in high quality. i'm on xtra broadband and i get about 3Mbps on speed tests but according to youtube my speed is slow so they automatically give me the lower quality video. here is how to test on this url>>

if this video automatically plays for you in the lower quality it will say "Watch this video in higher quality" underneath the video.

i wonder what the benchmark youtube is using for connection speeds.

anyway i clicked on the higher quality version of the same video and it is so clear it looks like tv quality. took longer to load but it's worth it.
