MOD is a format containing MPEG-2 video and AC3 audio. The extension is rarely used, that is why it can be opened only with special programs. Also MOD files can be playback by DVD players. If you want to open it with a standard player, the easiest way is to convert the file to MPG. Usually the format is used by Panasonic and JVC for recording video, the data is saved to a hard disk or SD card.

8-Bit Sampled Voice (8SVX) is an audio file format standard developed by Electronic Arts for the Commodore-Amiga computer series. It is a data subtype of the IFF file container format. It typically contains linear pulse-code modulation (LPCM) digital audio. The 8SVX subtype stores 8-bit audio data within chunks contained within an IFF file container. 8SVX subtypes can exist alone within IFF file containers (audio only), or can be multiplexed together with other IFF subtypes, such as video animation streams.
