How to Play MP4 Files on a CD Player
Playing MP4 files in a standard CD player requires burning the MP4 files into audio CD format. However, many newer models of CD players will directly play MP4 files without using an actual CD. Some players are equipped with USB ports so you can simply plug and play the MP4 files from wherever they're stored, such as a flash drive. There are also those with auxiliary inputs so you can play MP4 and other audio files using your mobile phone or portable media player.
Playing MP4 Files Using a Standard CD Player
Open your MP4 files in a CD- or DVD-burning software application to burn an audio CD copy. Because of their more practical use and features for burning both CDs and DVDs, most people use DVD-burning programs instead of CD-burning programs. However, both of them generally have the same disc-burning requirements. You may also choose an audio playback application, since many of them have CD-burning features as well. iTunes is one of the most popular programs used for this purpose.
Arrange your MP4 files according to the order you want them to be played by the CD player. Depending on the program you use, you can utilize the drag-and-drop functionality or click the up and down arrows accordingly.
Press the audio CD option in your burning program and configure the burn settings you want to use for the CD. Although the settings may differ from one program to another, the basic settings used in every program include: your preferred audio CD name, the number of discs you want to burn and the writing speed you want to use for the burning process.
Click the "Burn" or "Record" button to confirm the start of the burning process. The button name depends on the program used.
Playing MP4 Files using a CD Player's USB Port
Copy your MP4 files to a USB flash drive. After finishing the process, unplug it from your computer.
Insert the flash drive into your CD player's USB port and wait for the player to recognize the external device.
Select the MP4 files you want to play, then press the "Play" button. Depending on the CD player manufacturer, model and features, you may also be required to press additional buttons such as changing the playing program from "Audio CD" to "USB." Some may have "Autoplay" functionality.
Playing MP4 Files Using a CD Player's Auxiliary Input
Copy your MP4 files to your mobile phone or portable media player such as iPhone, iPod or MP4 player. After finishing the process, unplug it from your computer.
Connect your mobile phone or portable media player to your CD player via the auxiliary cable and wait for the player to recognize the external device.
Browse around to find the MP4 files you intend to play, then press the "Play" button from your mobile phone or portable media player.
