bad drivers can cause the tab to become unstable. it happens more frequently against the VZW model.
this is exactly why i said, one should not look at youtube HD as a benchmark to how the tab is operating. hitting a menu item and waiting 3 seconds, that's an issue or swiping and waiting for it to do something, that's an issue. looking at youtube hd and it pausing for a second or two, that's pretty much always happened (depending on the content and/or network speed (less so)). usually just micro stutters tho.
I accept your explanation, but I guess I will never understand it. Something like this should never happen. Because this means I could just connect the device once to a manipulated PC to make it unusable.
Normally I would totally agree with you. I never care about youtube performance issues. But this time the reason was the high cpu load and not network or content. I've seen the log files. Hopefully this is fixed now.
