Cavalary: The lack of infinite loading is a good thing.
And that thread shows up on the first page on a search for either "covers" or "DVD". In fact there are only a handful of threads with "covers" in the title, and still less than a page with "DVD".
About infinite loading, perhaps it could be toggled on and off, based on the user's preference. But for finding a somewhat recent tread such as the DVD covers one, it could be helpful.
About the search function, in this case, it's indeed feasible to find as it is now, but only because there are few threads to cause noise. If such themes suddenly become hot topics, the amount of noise in the results of a forum search is likely to increase too, making finding anything relevant harder and harder.
