The latest version of the PSP firmware gets you RSS feeds, specifically podcasts. Sounds good, but there are a few problems. The first is that the PSP doesn’t actually download the podcasts, it “streams” them. So you need to have a Wi-Fi connection at all times. The second downer is you need to use their interface to add each podcast feed. There is some hacking of the file format of the stored feeds, here’s the first pass at cracking it at bit – Link. Ideally, you’d have a desktop OPML to PSP-RSS list creator and also, Sony should consider making the PSP actually download the files so you can take them on the go…I don’t think I’ll update to 2.6 until this is fixed.
