streamripper crashes on start (more info)

[bootdoc]

when i click the record button in streamtuner, a shell opens for a couple seconds then closes. too fast to see any errors. how do i configure stream tuner so that it will rip the stream?

Edit:
dmesg | tail gives this:

I googled some of this and only come up with cd/dvd r issues. why would streamripper error out on optical drive issues?
