All of the systems that you list are cheap and crappy, with pitiful sound, lousy build quality, lacking in connectivity, and made so cheaply that they will break very soon.
If you want GOOD home theater, loosen the wallet and be ready to spend around $400-$500 as a minimum. Good audio receivers for home theater are made by Pioneer, Yamaha, Denon and Harman Kardon. Good speaker are made by companies such as Infinity, Polk, JBL, and Klipsch. Good separate disc players are fine from Sony or Samsung, as well as from Panasonic and Pioneer.
A Polk 6750 5.1 speaker set can be had from Newegg.com for $170. A Yamaha 373 5.1 receiver can be had from Amazon for $188. Good BluRay players can be had for as little as $65. That combination will blow away any of your chosen cheapie systems, will sound better, will allow for more gear to be connected (Game systems, etc.), and will ling outlive the cheap crap.
