well the panasonic hometheater system sound be great and the picture be great , however the pop sound only appear when i play my vanilla sky , matrix reload and l.a. confidential dvd 's . the first 2 dvd title show a small amount of pixellation ... there like little color square that appear for less than a sec and sometimes interrupt sound but not everytime i play the disc .  i try those dvd 's on my sony dvd player and the disc be perfect . no scratch , no fingerprint , no pixellation and no dust . my l.a. confidential dvd never play well with the panasonic system , with the sony it be perfect . if someone can tell I why i get this little color square but the disc be perfect .  this panasonic home theater dvd really disappointed I when i play those disc , and how now what other dvd 's get those little annoying square and what annoy I the most be that they dont always appear on the same chapter , sometimes not at all and sometimes they do appear .   1 star for the problem , cuz the sound and picture be great but the little square really tick I off . be there something i can do to stop that from happen ?
