I buy this just the other day and hook it up with the include a\/v cable and it work jut fine . then I go out and buy component cable to take advantage of the system 's Progressive scan capability . I hook it up and try to watch the lord of the Rings Extended Edition . it work fine and look amazing but then I switch it to DTS and there be a random loud thumping noise come from the subwoofer . it be very audible and very distracting during quieter scene . it sound like someone rub they hand over a inflated balloon . I check around on the internet and find a few other people have this problem . one of they speak with a customer service representative and he tell he that this happen because DTS and Progressive Scan be not compatible which sound crazy to I . we think it be a design flaw . I have email customer service myself and I hope they can help I but until then , be very wary when consider this system . if you do not have a progressive scan tv , do not worry about it and get this system which be actually a very good deal . if you want progressive scan and DTS -lrb- my personal favorite audio language -rrb- then avoid this system until Samsung get this work out . any help you all can offer will be appreciate .
