I have be use a Panasonic sc-ht740 5 dvd home Theater System for about nine month and I have be very satisfied . I enjoy my home unit enough to recently purchase a second sc-ht740 for work . here be seven benefit and drawback . benefit : 1 -rrb- the sound quality be excellent when play cd , cd-r , dvd , dvd-r and the radio . 2 -rrb- the bass can be adjust to multiple level . 3 -rrb- the tv 's audio signal can be play through the system . 4 -rrb- the theater can be expand to use a second room speaker . on one of my unit , I use the  sh-fx80  it have issue , but it be worth it . on my other system , I use the  sh-fx60  it work very well . 5 -rrb- the unit hold five disc . 6 -rrb- the system will accept a ipod . 7 -rrb- the unit be physically attractive . drawback : 1 -rrb- the remote control have so many feature that it be difficult to learn and use . 2 -rrb- there be no way to access different video angle . my old dvd remote have a button to select different angle for compatible disc . 3 -rrb- other than the bass level , there be no equalizer to micro-manage the audio signal . 4 -rrb- the remote do not work with my Sony television . 5 -rrb- the sh-fx60 -lrb- wireless rear speaker kit -rrb- and sh-fx80 -lrb- second room speaker -rrb- can not be use on the same unit simultaneously . 6 -rrb- the system be not compatible with pal or sacd disc . 7 -rrb- I often get wavy line on the screen for about five minute . customer service tell I to change the yellow video cable . I have use three different cable -lrb- one of which be gold plate -rrb- and the problem persist . instead of the cable , it may have something to do with the main unit .
