I have Windows 7 Ultimate, and recently, when i try to play a song off of my Twonky Media Server/Windows Media Connect (based on an HP WHS with an Atom), it plays choppily. When i open Resource Monitor, it shows that after ordering the music to play, memory usage rapidly spikes to consume most, if not all, of the available memory on my system (excluding a couple hundred megabytes in standby). Why does it do this and is there anything i can do to stop it?

Edit: it happens when I attempt to browse the server's music, not just when i play music.

Edit 2: the "ehshell" process is what consumes the memory, appears to me something specific to media center. Moreover, the ehshell process doesn't die in this case.

Edit 3: It only happens when browsing my Twonky library, and not my Windows Media Connect.
