I recall reading somewhere that there's a special build of a different emulator (not pj64) that runs it at 60fps, not sure how you'd go about accomplishing that on PJ64 though. Someone else here may have more information on that.
Also keep in mind that, unless your PC monitor is nearly as large as your HDTV, one reason why it looks better on your computer is most likely that the image is being stretched over a significantly larger area on the HDTV; think of it as zooming in on a picture in mspaint or photoshop; it's going to show up with much rougher edges than it would at its normal size. For games that are pre-PS2/Gamecube/Xbox I always recommend connecting your PC to a CRT (tube-style) TV and playing them on that; they act as a natural "filter" and make those games look as close to how they originally looked as possible.
As for the popping sound, you can try running a newer version of Project 64, as 1.6 is quite old. You can find the latest version on their official website here.
"I think that the problem with this video is it is highly derivative of many popular bands within the genre. Although when viewed on its own merits, it does have a deeper groove. However what it has in groove, it lacks in originality. One can't help but be reminded of such bands as Pearl Jam, White Zombie, Suicidal Tendencies and other bands that bear the mantle of so called "Alternative Rock". One is even reminded of Lorie Anderson when she wore curlers. Hehehmhm! This video speaks less to the heart and more to the sphincter. In closing, I think Korn would do well to learn more from -"
