I have a 15" late 2008 MBP. The primary usages for my computer are: internet, and watching recorded TV shows from my laptop to my TV (I have my MBP hooked up into my TV). Given that I want to store all of my DVD's on my computer, and I also download and watch TV shows (in .mkv format) on my computer, I'm looking for some advice on how to best use my MBP to organize, and watch tv shows. My questions are to people who have similar usages/setups on their MBP: 1. Did you upgrade the HD for storage? If so, what size do you have? 2. What program do you use to manage your media? Since the files are in .mkv format, I can't use iTunes (which I use for music and audiobooks). 3. Is their a better HD format than .mkv to watch these in? Would I be better off converting into iTunes compatible format? Thanks everyone for the help!
