I'm sure there are some techies here who can advise me. I have a Toshiba Gigabeat MP3 player that I received as a gift a couple of years ago. I've never had another MP3 player and I've been pleased with this one, but I just discovered something very disappointing. After downloading some free audiobooks from Librivox, I discovered that they will not play on my Gigabeat. I can't even get them loaded on the device, but I read online that it does not support most audiobook files. The files are named .mp3, so I don't get it. Before this I didn't even realize there were so many different file types. Another factor I need to consider is that my DH recently gave me a stereo with an Ipod dock. It will work with my MP3 player with a cord in the PC mode, but it would be nice to have a player that would just dock on it and therefore be compatible with the remote. It's a Sony stereo and appears to only be compatible with Apple Ipods on the docking thingey. Now, can this be solved by finding some sort of conversion program, or am I going to be forced to purchase a new player if I want to listen to audiobooks? If I find this conversion program, I wouldn't even know what I need to convert to/from. If I buy a new player, which ones have the most formats?
