I have a good decent laptop 2GHz, 700MB memory, and a puny 30 GBhdd. The only problem I am having with it is that I am trying to run a series of video training in the cd/dvd player. I can allocate all the memory I want to the C drive but not the D drive. The audio skips and since this is going to be about 20 hours of training, it's going to get annoying quick. Is there a way to allocate cache to the cd/dvd player? thanks.
