I go to Jimmy Akin’s blog a lot, who works for Catholic Answers, but I could never listen to the radio call-in shows that he would put up on his site because they were in Real Media (.rm) format, and I refuse to use Real Media player due to its annoying adware-like behavior and cpu-sucking processes that sit in my taskbar. Fortunately, they are now trying out the mp3 format for their radio shows, which just about any music player can play (itunes, Windows Media Player, etc.).
