Can you post the log from /home/usr/MyDocs/mlboutputlog.txt and have you looked for the /usr/lib/.mlb/config file to verify your settings are being saved?

From what I can tell from the original backend, the URL error is often a login failure.

Yeah, don't bother, that post is for an older version of mplayer, and it hasn't been ported to .27 yet. At first glance, there is atleast one library file not found, and I don't know where to begin and figure out how to patch mplayer. Guess we'll have to either wait, or you'll have to pray that I magically learn how c++ for Maemo...
