I bought a couple ASIC Block Erupters from CanaryInTheMine and plan on mining on my Raspberry Pi. I love using my RPi as a HTPC to play videos on my LAN and would prefer not do dedicate it to just mining. Does cgminer use so much CPU that I wouldn't be able play videos at the same time? I know, for HD videos, most of the processing is done on the GPU for video processing but some CPU must be used for fetching content on the network.

Can both cgminer and HD video be played at the same time?
