Since upgrading to flash player 10.3.183.5, whenever I watch a video on youtube and then click "replay", it reloads the entire video from youtube's website. My internet connection is quite slow and previous versions of flash would replay the video from memory/cache instead of re-downloading it.
Is this a known issue with this version of flash player? Is there a setting I could change to enable the cacheing of videos? Or is the problem with youtube themselves?
