Help me pick a speaker system
 

I am looking to buy a speaker system to use to watch dvds on my xbox but I am not sure which one to get. Two systems that i was looking are the Monster Game XG SSGS-500 5.1 Surround Sound system and the Inspire 5.1 Digital 5500D Console. There was another one I saw at Best Buy but I dont remember the model number. If anyone could help me pick one that would be great. Thx
