When making purchasing decisions I like to queue up a bunch of model previews and determine which ones really get me going. Sometimes these previews download fine, and other times the preview gets "***** up" where it will just stay at a certain percentage for a long period of time even if nothing else is downloading, they do eventually unfreeze and continue but I was wondering if there was something I could do to make these previews finish up faster, or prioritize certain ones? I don't want to spend hours looking at previews, I just want to be able to check out a few models and pick the ones I want to buy.
