Stick to the nightlies. The versions 1586 and 1696 are the two most stable builds.
Looking further into the nightlies and my distro, I see that Ubuntu’s version is based on 1696. The very latest set of updates appears to be http://archive.ubuntu.com/ubuntu/pool/universe/m/mt-daapd/mt-daapd_0.9~r1696.dfsg-4ubuntu1.diff.gz, which you can get from http://packages.ubuntu.com/jaunty/mt-daapd. Most of the changes look like improvements. The one that gives me pause is the ripping out of the Apple mDNS code. Can you tell me what you think of that?
many thanks again.
