[PROBLEM] Increase network buffer

[raspberry_pd]

Compressing RAM would make sense, if we needed it! At this stage, I am getting an instinctive impression that it is almost impossible to get the Raspi to use more than 100 MB of RAM!

Even on the so-called 512MB Raspies (which only show 401 MB available), I've not yet seen more than 100 MB used, no matter how complex the video is (that said, I've not played raw BD iso files).
