Procaster Lite?

[JustGLiTcH]

Im struggling to keep this stream going for a school : www.livestream.com/chmsbirdbox

Basically im fairly certain its because livestream uses 100% CPU and kills the program. I was going to suggest a "Lite" version of procaster, that has much less options in it but uses much less CPU. The only options i would need is the choice of desktop or camera. Is something like this possible? (alot of machines in schools have nowhere near the specs required, but many of them are interested in birdbox cameras).

Thanks
