hi rejetto,
the problem with that is that when you access the rss feed file you end up accessing a mp3 file in the protected music folder so HFS correctly requires a password for that too, so using a PSP fails on the feed.
One thing i have just thought of is that from my work pc i have accessed the passworded mp3s using winamp and it streamed them nicely enough.
i am wondering if a url like this
http://user:pass:86.123.145.56:port/music/name.mp3
might be a viable address that can be put in the rss feed file. then if the rss link is on a passworded web page, only the owner can access it.
i can't test that today as i havnt left my pc on at home (in at work now).
ill try tommorrow if i remember.lol... and let you know what i find.
cheers silky
