From the developer:
LizardTech MG4 Decode is a free graphical utility which provides you with the ability to decode LiDAR files compressed to MrSID Generation 4 (MG4) back to LAS or ASCII formats. The MrSID file format is a proprietary technology that provides tools for the rapid compression, viewing, and manipulation of geospatial raster and LiDAR data.
You may want to check out more software, such as LizardTech GeoExpress with MrSID, LizardTech MrSID Plug-in for ArcGIS 3D Analyst or Elecard MPEG-2 Decoder&Streaming Plug-in for WMP, which might be similar to LizardTech MG4 Decode.
