The codec is a computer program capable of encoding or decoding a data stream, in this case an audio file. Every piece of media data uses a codec, which encodes data for storage or decodes it for playback. Media data is encapsulated in a container file (Such as an MP3, Windows Media Audio, Apple Audio, etc.) and the codec decodes and plays back the media inside. Sometimes, the media playback device or program, in this case PS3, sees the container file and may not be able to decode the data within. This can happen if certain encoding settings are used, or the file is corrupted, or if there was an error in the encoding or copying operation.
Does the same media playback properly on a computer or MP3 player? Copy a song off of the PS3 and play back that same file on your computer to find out. The length of time your PS3's hard drive will last depends on the drive's age and how much you use it. For a desktop PC, a standard platter-based drive, which is what the PS3 uses, should last around five years.
