If it's taking two hours to download 100mb on a 1mbps account then
Switch to Openweb and you'll be a lot happier. Day or night there's no comparison.
I've noticed with Youtube that it'll stop buffering when you pause it so I cannot pause and leave an HD vid to buffer anymore. :\
Funny enough, some videos will buffer but only to a certain point when using chrome, others dont buffer at all, however firefox seems to be OK
AND
since last night youtube seems to be 10X better, have it set in 360P and the buffer bar is creeping ahead of the progress bar
