With HD DVD and Blu-ray finally hitting the shelves there are still a lot of questions to be answered before deciding on a format. Dan Costa over at PC Magazine has an excellent write-up of what you need to know when it comes to choosing a new DVD format. Thanks for the information, Costa. I even learned some stuff that was still a little confusing in my head. This is definitely worth a read for any home theatre nut—or any movie watcher for that matter. Knowledge is power!
