I also use a G3, and I've found that you'll need more than one application. No one of them seem to play everything, especially when it comes to MP3's. QuickTime 4.0 is OK, but you're forced to download it, and then be on the net to do the install. With a 56K modem, downloads aren't to bad. I would suggest RealPlayer Plus G2 & SoundApp PPC at a minimum. Another small but good program is SoundMachine. Links to all of these should be found at . I've been thru' it all, so if you have a problem, feel free to e-mail me at bleudenim@yahoo.com. Be happy to go into more detail.
