Although this Epson projector lacks a "smooth motion" feature, understand that's pretty much the case for all under $1000 home projectors. Beyond that feature, consider the Home Cinema 710HD to be an excellent, bright 720p projector for sports viewing. That would even be in your backyard at night for Monday Night Football - so don't forget, it has sound built in.
As a 720p projector it's just fine on all good things HDTV, except, lets separate out movies. Movies viewed on HDTV are still movies. Movie performance, will essentially be that of movie viewing off of Blu-ray, except of course for the slight loss in picture quality coming from your satellite box or cable box. As such, I'm really not describing movie viewing performance in this section. More of sports, plus The Simpsons, CSI, Fashion Police (if you are willing to watch low def), CNBC's Mad Money, DiscoveryHD, and Paladia, to name a few great channels that span a wide range of content.
This Epson is an excellent, fun, bright projector for the home. Invite the friends over, watch some Pro sports, watch the Olympics (just starting as I write this), or your fav sitcom. Have fun!
