we finally get around to mount the speaker up properly , only to find the unit do not work properly . it will read low-budget dvd like `` little rascal '' collection -lrb- buy at Christian bookstore -rrb- and a music tutorial dvd , but it will not read any dvd rental or purchase from Blockbuster and the like . the unit only show the `` no disk '' indication . the only menu I can get be the general menu option when dvd\/cd player be select . DSP , equalize , and other button do\/indicate\/select nothing . this statement on Amazon and other seller ' site be a lie : `` Dolby Digital 5.1 and Dolby pro Logic decoding ; Dolby pro Logic II generate 5.1 surround signal from any stereo -lrb- 2-channel -rrb- source '' the unit default to stereo mode when aux 1 or aux 2 or select , so there be no way to get surround sound from this thing except if it be encode on a dvd that will actually play . nothing in the manual or on the box support the claim of the seller that it will `` generate surround signal from any stero -lrb- 2-channel -rrb- source . '' this be a figment of a sale ' department imagination . I be severly mislead into buy this junk because of this false claim as I be specifically look for a cheap way to get surround sound into that room . the previous homeowner leave hole in the wall from they home theater , but since this be a room we do not use much , I opt for a cheap way to cover the hole with speaker and bring surround sound to my directv viewing\/cd playing in that room . add to that the fact that no rental dvd will work , it be a extreme ripoff . of course the receipt be nowhere to be find so I can not even have the unit service under warranty even though I have the box , UPC , and manual . even if I do , I suspect I will be tell that the disclaimer in the manual be interpret to mean there be never any guarantee the unit would play -lrb- undamaged , clean -rrb- rental or purchase commercial dvd 's .
