Will these old time radio shows play in my MP3/DVD player?
Maybe - it depends what brand of MP3/DVD player you own. The old time radio shows should work fine with MP3 players that download the shows through a USB cable through your computer. The CDs themselves will definitely play in a Riovolt player and in your computer using the program WinAmp (available for free at www.winamp.com).

Unless you're using a Riovolt brand player, I cannot guarantee that your player will play the radio shows without problems. Many MP3 players say they will play all MP3's, but simply will not play certain MP3 bitrates (most OTR is stored at 32kps 22khz bitrates - if your non-Riovolt brand can play these specs, they should work fine, but not always). The only reliable MP3 player I can recommend is the Riovolt MP3 CD player or they will also play on your computer without any problems.
 
 
 
 

What MP3 player is recommended for playing these shows?
I recommend the Riovolt player which is a portable Walkman-size CD MP3 player. It plays all different kinds of MP3 bitrates. I purchased a Riovolt and a cassette adapter and which works great to play the old time radio CDs in my car. For users with a cd player in their car, one user reports hooking up the Riovolt to the Sound Feeder device works great. The Riovolt also will display filenames/MP3-IDs and has a number of great functions such as resume play, pause, and fast-forwarding, rewinding and a small LCD screen that will visually display file and episode titles.
