Pelco is one manufacturer using this format. – rsaxvc Nov 28 '14 at 5:46

Sorry to disappoint you, but .dsf looks like it may be a sound file.

Have you tried VLC? It's not on the list of supported formats, but still might be worth a try - and always useful to have VLC installed anyway.

It's a video file. Pelco and other CCTV DVR brands use them. Current VLC does not play it. – rsaxvc Nov 28 '14 at 5:43

Download FFMPEG (there are sources as well as binaries for every system)

then do this: ffmpeg -i myvideo.dsf

It will show you what codecs are in there. After you know which, you can try getting that codec and playing the file.

no luck, FFMPEG reports "C:\Users\Crom\Downloads\10000004D.dsf: Invalid data found when processing input" – rsaxvc Nov 28 '14 at 5:46
In that case the file could basically be broken.. – sinni800 Nov 30 '14 at 16:31
It played fine on the dvr. – rsaxvc Nov 30 '14 at 23:29
