Thanks for the reply. That is weird then because it has happened at least 5 times. Could it be some sort of setting conflict? My guess was that the new temp file from the loading song was having some sort of conflict with the one being encoded.
I'll try to get you some more info if I can.
EDIT: Here are my current settings. Another quick question, to everybody I guess: Has anybody else had PandoraSaver crash when encoding MP3s to 320 kbps? I tried to, but mine crashed. I think 192 is safe, though I haven't tried any other bit rates in between.
