BD Players

Anybody have advice on how to own one without throwing it out the window and shooting it? Mine is less than a year old and apparently becomes dated quicker than a computer. It won't play Law Abiding Citizen (which I rented from Blockbuster). I assume it needs a firmware update, but am not sure how to update it (i.e. what is the best way). I tried downloading the update from Sharp last night and my computer basically froze while trying to copy the file to write to a CD-R. Thanks!

 

Whoops! Didn't realize I posted this in the wrong section. My computer is an old HP mx75. I forget what the video card is. I don't think that has an effect on downloading a file to transfer to the Blu-Ray player though, does it?
