You could go with either an Epson MovieMate 72 720p
HD LCD projector (consider connecting an OPTIONAL Polk Audio wireless powered subwoofer to the subwoofer output to experience DEEP BASS) or the cheaper Epson MovieMate 60 540p
LCD projector, and Da-Lite's 90 iNCH diagonal 16:9 portable projection screen. You'll be able to show DVD movies and play music CDs. To the HDMI input, you could connect a wireless networking Roku HD-XR player for streaming Amazon VOD, Netflix movies, Major League Baseball, and more!
