With PR 1.1 I could point to my M3U playlists from links in a locally stored web page and the media player would open and load the playlist. This was pretty handy as I had one page I opened that contained album art images that I used to link to the corresponding playlists. This is broke in PR1.2. The M3U's now open as text files. I hope that gets fixed or I figure out where to make this association again.
