Do videos from other sources lag?
does YouTube lag on other devices using the same wifi connection? (Assuming you're on wifi?)
Try going to settings, applications, YouTube, clear cache, and do the same for the browser.


dnyeah,
I'm not sure which version of the YouTube app you have, but if you look at the market there are a lot people who posted reviews with similar problems (2.2.16 and even prior to this one). This is why I have not updated my version through the market and I have uninstalled updates back to the stock ROM version 2.1.6.
If you have a newer version since you updated the firmware (mine is still 2.3.3) then it's possible you picked up these newer versions that have some kind of issues? I don't know what the issues are - it's just enough for me to not update based on experience others are having?!
I went back to stock rom but it still LAGS!!I don't have any lag with miui wtf
Like you said it might be the kernel - have you tried a different kernel?
How do I install a different kernel without rooting? I want it to be stock please help me.

If you've already rooted, why do you want it to be stock? Your warranty is void now that you've flashed custom software.. you can't undo that without buying a "USB Jig" (and even that doesn't work sometimes).
But yeah, you can't install a different kernel without root access so it's not possible.
I'm not sure what else to suggest, I would have suggested that you have your device swapped but you probably won't be able to now that you've flashed a ROM![]()
