Panasonic SC-HT900 .  my Rating : FRUSTRATING  I buy this unit new in the box from Circuit City for $ 479 in July 2003 .  the good : sleek design for a small cabinet volume . speaker be unobtrusive , they do not hog my living room . hold 5 dvd with progressive scan capability .  the Bad : 1 . if a dvd be play , then when any other input be select -lrb- such as tv to check sport score , or FM -rrb- , the dvd player stop and return to the main menu ! that be right , it have no knowledge of where it be in the movie if you either mistakenly or intentionally change the input .  2 . from the remote , it can be put into a mode where no sound come out when play a dvd even though the video portion appear on the tv . select fm or turn the unit off then on will force it to output sound , but again , you have lose you place in the movie . when in this silent mode , other button on the remote do not , by themselves , force audio output . perhaps a sequence of button push will wake the amplifier up , but I do not have the patience to try sequence .  3 . the confusing remote have some button whose sole purpose be to control other component -lrb- if Panasonic provide code for you particular unit -rrb- . the AV System button can turn you tv on but it do not select the tv input on the sc-ht900 . tv\/video can change the video input on you tv , but it do not select the tv input on the sc-ht900 . several button function be shift . you have to hold down the shift button while press another button . this be a three hand operation . one hand to hold the remote , one hand for press the shift button , and one hand for press the desire function . good luck ! the button on the remote be discrete , whereas those on the receiver be toggle . the receiver have disk skip , on the remote you must press disk then a number between 1 and 5 . the receiver have a source Select button that toggle between the 7 input , the remote have 5 unshifted button and 1 shift button for the same purpose .  4 . the amplifier be too weak and fail at normal loudness level . the volume function be calibrate in db from -68 to 0 . at any level above -22 on my unit , the amplifier will eventually fail while watch a movie or listen to a cd . at -20 , this typically take about 45 minute before a loud POP be hear through all speaker follow by a severe decrease in volume . after a few seconds , the volume return to normal . several minute later , another POP be hear , and the sequence repeat with the interval become shorter between pop . I assume my unit be defective in this regard , but I have not want to extract the unit from its cabinet to take it in for service . I play movie and cd at setting -22 and below .  5 . the optical digital input on my unit do not work . no sound be output , although the front panel light be light , indicate that the optical input be select . this input 's sampling frequency for Dolby Digital be suppose to automatically switch between 32 , 44.1 , and 48 khz rate . I have try connect a few optical output device with two new cable . my sc-ht900 do not output any sound when the optical input be select . two other surround system in my home work fine when connect to the same component with the same cable .  since it be still under warranty , I be take it to a service center to get item 5 correct if possible . since it take more than a half hour for the problem in item 4 to happen , I do not have much hope of get it fix . since the dvd player and receiver be in the same thin unit , and the amplifier be in the subwoofer enclosure , I have to take both unit to the shop . if they be not repairable , I 'll have to get a new receiver and a new subwoofer . the subwoofer do not appear that it can be drive by a rca jack or otherwise from a standard surround sound receiver . I wish I have consider the interrelationship and marriage of the dvd\/receiver and the subwoofer\/amplifier when I buy it .
