I guess my other option is to split the large files into multiple smaller files >4.7 GB and burn multiple DVDs. Since DL DVD's are so much more cost wise then regular DVD's this may not be a bad idea on my part.
I've heard the WD are good but since I already have a wifi network setup the Popcorn would be great and besides it's built on a Linux OS (at least that my understanding). I already have a 320GB external HDD and a 1TB external HDD which is around half full now.
Thanks for your help and responses though. We'll probably laugh at threads like this 10 years from now at the fact that we were discussing physical media and different ways to do things with it.
