I purchase this system because it combine a up-converting dvd and hdmus in\/out function . if you be look for a smooth operation out of the box , this set be NOT for you . here be my concern : - cable connection to the speaker have a proprietary type plug on the back of the system . if they length be sufficient , then there be no problem . Troble be if you need you speaker farther away or need to go around the room to get to they . you can not buy the connector anywhere and Samsung only sell they along with the cable and , once again , not for longer run . I have to solder cable to the connector -lrb- after have rip apart the plastic on they -rrb- to be able to get to my back speaker - I use my HDMI in\/out function , connect the tv hd box in and connect out to the tv . this connection never work . I have to revert to connect my tv hd box directly to the tv via HDMI and use component video for the dvd\/home theater set . this be quite annoying because this be one feature I be look for since my hdtv have only one hdmus input . the problem seem to be in the connection of the two hdmus plug on the theater system since I could see my dvd out of that . if you tv have two hdmus input -lrb- as the most recent have -rrb- than you have no problem . - connect the audio from the hd box set via optic cable . this connection sometime loose completely the signal and I have to ` circle ' again through all the input option -lrb- aux1 -rrb- aux2 -rrb- hdmus -rrb- DIGITAL in -rrb- just to get my audio back on . this happen quite often when you switch channel a lot . - sync problem between image and sound : with the digital connection , I seem not to be able to precisely sync the image and sound - remote seem to be `` swallow '' battery power . first set of battery last two week , I then buy rechargeable battery but need to refresh they charge every two week or so . compare with other remote where battery life be at least six month . overall , a economic system that show all he problem .
