Just to give a followup on this so ppl searching the archives might find something useful .. I am now using the ck-sources kernel which contains the Low Latency patch, the preemtible patch, the O(1) scheduler from 2.6 and a few other goodies (I just decided to go the easy way since I am a gentoo user and ck-sources is available without myself needing to do any patching). So far the result is _very_ satisfactorily, thank you for the pointer! I haven't done any recording yet, but so far there were absolutely no glitches in playback any more. What a difference!

Apparently this has been fixed (it uses "default" now) and it is working nicely. Well the gtk interface is kinda .. uh .. not so much to my taste, most of all since it sometimes hangs a little (upon encountering playlists with entries that can't be played), but the text interface is fabulous, and the streaming works very well.
