Dear Lifehacker, When should I choose standard definition over high definition TV shows or movies from iTunes? Right now I have a Sony 1080P in my bedroom and a 42" inch 1080p screen in the living room. Often I'm unable to see a major difference between the two definitions. Any advice? Cheers, Redefined

The visual benefits of high-definition video are dependent on a range of factors, including the size and brand of your HD screen, the quality of the video transfer (especially for older movies) and the distance you sit from the TV. It's also possible that your HD display is badly calibrated, which could affect the image quality — click here to read our quick-fix guide.
In addition to all this, the perceived beauty of HD is very much in the eye of the beholder: some people refuse to tolerate anything less than 1080p, while others don't really understand what the fuss is all about. In your case, it sounds like you're pretty happy with DVD quality, so there's very little reason to waste the extra money and bandwidth on high-definition downloads. We'd stick to standard definition.
On a related note, buying on DVD and ripping the content may actually be cheaper and more flexible than relying on iTunes for your movie fix. You can read a guide to the best DVD ripping tools here.
