For everyone having YouTube HD problem:
The lag and stutter have been there since Samsung's crappy ICS update, and for some reason, every single custom roms also have this problem (at least for me). ONLY honeycomb based Roms have smooth YouTube. So it's not Rom related. And you may not have experienced this issue with previous versions of this nightly, but it was probably that you watched different videos, which don't lag that much, as every video is different on this tablet. Some lag horribly, some ok, some smooth. Videos like music concerts where the camera pans around a lot lag really bad. But for videos where the camera is still and objects are moving are less leggy. And very weird thing is that action movie trailers, which move super fast are smooth as butter. So we don't really know the problem.
I don't think you guys should blame this Rom for the YouTube HD problem. I have had it in every single Rom (ICS, AND JB) EXCEPT for honeycomb roms.
