Let's see...New and decent will be tough. Much easier to do if used. 2 Pairs of B&W 302s or the new 303 ($500 new, $350 used). B&W CC3 center ($180n/$130u) HSU VTF-2 subwoofer ($50O new, $400 used). Onkyo HT Receiver ($300 to $500 depending on power, the B&W speaker will not need a lot). Pioneer DV343 DVD Player $200 (it will play most formats like CDRs also). $50 for standard 12AWG speaker cable (bulk roll). $100 for decent interconnect and video cables, etc. $125 for Monster HT2000 power center.
