Sony has released an updated version of its Media Go
application for Windows-based PCs, enabling them to play back video content purchased or rented from the PSN video store -- in standard definition only. Apart from that headliner feature, the app can now queue up multiple PSN store downloads simultaneously and automatically assign them to sortable categories once downloaded. In addition, it's no longer necessary to have your PSP connected to your PC via a USB cable in order to download PSP games, demos and videos.
