Thanks, but that doesnt really answer the question at all!!! When browsing from the 770, and clicking on an mp3 file on a website, why would it save it as an m3u. What i dont understand is that it goes through the whole process of downloading the full 23Mb mp3 file (about 4-5 minutes) but when i browse to the file on the local device all i get is a 1Kb m3u file. Very strange.
