Please start with CSSU version, bluez version (dpkg -l bluez) and obexd version (dpkg -l obexd). Feel free to use HAM instead of command line.
[EDIT] 1) file browsing problem should be related to the bug in CSSU obexd: http://talk.maemo.org/showpost.php?p...&postcount=539 You can find the fixed package in cssu-devel or http://merlin1991.at/~luf/obexd/ 2) I'm affraid that multimedia part in bluez is quite old. I see a lot of improvements in newer bluez version. It's highly experimental but you can try it (I'm using it more than one year): http://merlin1991.at/~luf/bluez/ However I don't use the multimedia part. [/EDIT]
