Why Blu-ray? There are very few players that were bought, Playstation could play back, but with domestic burners you are limited to how much you can burn, the biggest draw back to Blu-ray and Steve Job's bag of hurt was the crappy cost of licensing rights, it was very very expensive to burn a batch of Blu-ray disks, hence many studios only put onto blu-ray high value movies.
Stick to dvd, any way, dvd and if you manage to get blu ray to work, it will be at best a high quality standard def version of your movie..
