DR td,
Some regular DVDs I've noticed are VERY good up-converted:
HELLO, DOLLY!, DOCTOR DOLITTLE, THE KING & I, FLOWER DRUM SONG, THE FIFTH ELEMENT, STARGATE, (surprisingly) the later Charlie Chan films from Fox, SINGIN' IN THE RAIN, MEET ME IN ST. LOUIS, CASABLANCA, GOLDENEYE (or any of the James Bond Ultimate Edition releases), STAR WARS IV and V, V FOR VENDETTA, GYPSY, FUNNY FACE, SUNSET BOULEVARD.
