I think this is the proper place to post: "Installing and configuration of addition software not included in KnoppMyth." So no worries
I wanted to thank you for asking this question - I didn't know about streamripper until just now
I knew of 
Windows programs to do this, but no Linux ones.
I have half your problem solved. If you do this:
Code:
streamripper http://oggtrial.nm.cbc.ca:80/cbcr2-toronto.ogg -a -l 30600
you will get files named, e.g.
Code:
sr_program_2005_09_08_17_09_08.ogg
inside a directory named
Code:
CBC Radio Two Toronto
If you tell me what naming convention you want, I can help you fix the script to do that, but I'm really not sure what the -D parameter is for, since I found no reference to it in the streamripper man pages. Did you mean -d instead?
As for why MythMusic choked on it, I'm not sure. Mplayer did not choke on my test sample, but it did complain a bit:
Code:
Ogg : bad packet in stream 0
Maybe MythMusic has a stricter ogg implementation?
In any case, the docs on streamripper say it's for ripping mp3s from shoutcast-compatible streams. Since the stream you're ripping is ogg, maybe it's luck that it works at all? Is the stream shoutcase-compatible?
