I buy this system for my bedroom and it be unique from all the other `` home theater in a box '' system that I could find in that it have a component video input . I need this because my cable box support hdtv through component cable . the Samsung provide this feature with its `` digital in '' input selection and nicely pass through the component video throught its own component video output . I do not need or want the dvd changer but the lesser Samsung model leave out the component video input . I find use the changer a little bit of a hassle to insert and remove single dvd and it seem slower than use a single tray . the speaker be nice and small and that be what I be look for . the microphone to auto-balance the sound be a really nice feature and work well -lrb- it be all automatic -rrb- . I do not have any real opinion about the sound quality of the unit and speaker -- it seem fine to I but I be not good at evaluate sound quality beyond verify the 5.1 sound . the wireless rear speaker be a interesting gadget and do remove one set of wire from the unit to the rear . this really do not matter much to I -lrb- my unit be place against a side wall so run the wire across the floor be not horrible -rrb- . I do notice that there be some periodic interruption of the rear sound even within the small size of my bedroom . I rotate the receiver and it seem to make it go away during the sound test . I ultimately return this unit because it be incompatible with dvd-rw that I record from my Tivo in a different room . I be pretty surprise that such a new unit would have this incompatibility -lrb- I have see some older computer laptop have the same problem -rrb- . because of this , I have to attach a separate dvd player and this defeat the advantage of the small , all-in-one unit . I also could not take advantage of the component output of the dvd since there be only one component video input on the unit . since it do not upconvert composite video i also have to change the tv input when I switch between cable hdtv and play my dvd-rw . so for I it be just a lot of trouble . I give up on the idea of a combined unit and get a separate a\/v receiver with a separate 5.1 speaker set . more cable , more component to stack .
