You may find that you will need your sound projector professionally tweaked to get decent surround sound effects. I spent an afternoon watching my buddy tinker with one while I drank beer and was the dedicated listener. Never really got it right.
I came back the next weekend and he had the guy from the AV shop come and set it up. I did now hear surround effects alright. He definitely knew some secrets we couldn't figure out. I'd still take an actual 5.1 system over the projector any day but pleasing the wife is important and it does look cool under a TV.
