I have own this device for about 4 year now . most of these review up here be good enough to describe how it work , but if you be technically incline , please read on . use the device as a receiver be definitely not recommend . in Dolby pro Logic mode , delay can be anywhere from 40m to 80m . with Dolby Digital , the delay be worse -lrb- roughly 160m to 180m -rrb- , so voice seem can be delay . this be definitely noticeable when watch standard definition channel as they be not in Dolby Digital . mouth move and then voice come . however , if you plan on use this with any video game , be warn . be sure to calibrate you game -lrb- Rock Band and Rock Band 2 allow you to adjust the delay in video and audio separately -rrb- . without the fact that be play dvd , I would have rate this a 2 star . but since it play dvd well , I have to up the rating . dvd playback be good , but it lack the tech that come with today 's dvd player . back in the day , this be a decent product . now , it be time to move on .
