These days hip-hop nostalgia is in full swing: Pioneers like Afrika Bambaataa and Kool Herc are heroes again, thanks to an onslaught of books, films, and albums that wax sentimental about hip-hop's heady early days. (For Hova's sake, even the hopelessly buffoonish Breakin' 2: Electric Boogaloo has just been reissued on DVD.) So it's no surprise that someone has chosen to release a new, updated DVD version of the seminal 1983 documentary STYLE WARS (Plexifilm, $27.95), which plunged deep into New York City's burgeoning graffiti subculture. The film was first shown on the ever-educational PBS, and, not surprisingly, director Tony Silver's fascination with inner-city art comes off a little stiff and academic. Still, it is heartwarming to recall a time when graffiti, break dancing, rapping, and DJ'ing were fresh, electrifying, even dangerous.

For KUNG FAUX VOL. 1 (Tommy Boy Films, $19.99) the wacky, splice-happy filmmakers at Dubtitled Entertainment till the same soil that Woody Allen did with 1966's What's Up, Tiger Lily?, with similarly uneven results. The conceit -- to have hip-hoppers like Jean Grae, Mr. Len, and Gang Starr's Guru dub old kung fu movies in their own special slang -- sounds like a slam dunk, and it's realized through a combination of impressive quick-cut editing and funky graphic enhancement. Add to that a few choice grooves from Tommy Boy's legendary back catalog. The first two episodes, ''Ill Master'' and ''Boxcutta,'' are filled with hysterical and clever infusions of gangsta-speak into the rough-and-tumble doings of mainland China. But as with Tiger Lily, it's a one-note joke that, in this case, wears thin after a few too many ''Yo, dawg''s. Of course, this chopsocky stuff is directed at the doobie-toking dorm-room crowd, who'll no doubt be checking their giggles just long enough to inhale.
