.TP0 files are video files that have been created with the use of Mascom Personal Video Recorder devices. .TP0 files will typically contain a video recording that has been saved on the internal disk of a Mascom Personal Video Recorder device. .TP0 video files are saved in a proprietary format by the Mascom Recording device but can be converted to more common video file types (avi, wmv, mpeg) through the use of external conversion tools.
