Convert mp1 to wtv

What is the difference between .mp1 and .wtv?

Description: MPEG-1 Audio Layer I, commonly abbreviated to MP1, is one of three audio formats included in the MPEG-1 standard. It is a deliberately simplified version of MPEG-1 Audio Layer II (MP2), created for applications where lower compression efficiency could be tolerated in return for a less complex algorithm that could be executed with simpler hardware requirements. While supported by most media players, the codec is considered largely obsolete, and replaced by MP2 or MP3.; The WTV (Windows Recorded TV Show) file format is used by Microsoft's Windows Media Center to store TV recordings. Introduced with Windows 7 as a successor to the earlier DVR-MS format used by Windows XP Media Center Edition, WTV files allow users to record live television broadcasts or schedule recordings directly through their computers equipped with a compatible TV tuner card. These files encapsulate both the video and audio streams, along with metadata such as broadcast information and closed captions.
