we Have 2 New iPad 3 32Gig 4G's of which neither will play HD YouTube Video's unless your willing to pause and wait 15 minutes for them to load....VERY disappointing.
This happens even when using the apple iPad App. All lower resolution Vid's are just fine and load as fast as our laptops. Also, no problems with Wi/Fi reception playing Netflix or Hulu+, their beautiful and sharp as a tack...so this doesn't seem to be the Wi/Fi problem being discussed concerning Wi/Fi only models.
Unless I'm missing something, or anybody has a solution, I don't think the A5X Processor can Handle HD's heavy Packet loads via You Tube. If that's true then I'm upset! Best to all
