Miro, the open-source video client and podcatcher, has hit version 2.0. In addition to a revamped interface and various performance improvements in viewing and downloading, the new version also adds support for streaming shows on Hulu, CBS, etc. as well as audio podcasts.
As before Miro features a comprehensive content guide, YouTube downloading, and a built-in bittorrent client. Although you can cobble together most of Miro's functionality with other software, perhaps its biggest advantage is bringing together a bunch of disparate video sources from around the internet (many of them in HD) and putting them in a single, convenient interface.
Miro is a free download from the Participatory Culture Foundation.
