[LAU] recording webradio

assume some of you has lots of experience with this simple problem. I want (need) to record an internet transmission of a certain concert next sunday. I can receive the 'sender' and listen to it using vlc no problem. However, i cannot find how to save the stream to a file (eventually for burning). A big ptoblem is that the interface of vlc is completely different from the interface presented in the documentation. My system: AMD Phenom II (4-core) 4Gb mem. Ubuntu 9.10 (karmic). I have ample space to record (>1 Tb). Can anybody give me directions how to record this stream which has the following specs: Codec wma2; channels stereo; sample rate 48000 Hz; 16 bits. It is sufficient to burn it later to a CD. Joep
