they want to leave the buffer up because it seems as though they are in the mix stage, and keeping the buffer up will increase plugin count and drop the number of errors kicked off. Also it doesn't mention the model computer they are using, maybe they have an older model where using a high buffer is almost mandatory. The Mac Pro offers the power luxury of running low buffers most of the time, but I still crank it up towards the end of the mixing process and ESPECIALLY for doing bounces. There is nothing worse than getting 3/4 of the way through the bounce and getting a Buffer error. Manual delay compensation is a necessary evil in PT LE, so might as well learn to do it now. Here is a thread from a while back. There is some good stuff in it...
