Hello. For some reason, Google Reader parses VLC RSS (http://www.videolan.org/videolan-news.rss) posts with the wrong timestamp, as if all new posts were published in 2010. Because of that, no new updates show up for Google Reader users.
This has been reported to Google months ago, but nobody replied to the thread. Can you please take a look at your RSS code to verify if the problem isn't actually on your side?
