The only one might be the VGA issue, though there are adapters for component to VGA that you should be able to use with any player that has component video. The others should be quite common and easy to find. I think you will find it very difficult to locate a player that does not do dts at this point, and essentially all of them that have 5.1 analog outs should have the abitlity to internally decode it as well.
