I see. Well, I use tvheadend with a DVB-S2 receiver card (TeVii S464), which
works really well for scheduled recording or just watching TV.
If it is set to record to the Matroska (mkv) container format (the default),
it will also insert chapter marks where the stream parameters change
(e.g. a change from 4:3 aspect ratio to 16:9), which can be useful.

If you only need to cut these files, using mkvmerge (it also has a GUI program
called mmg) from the mkvtoolnix package, or ffmpeg, will probably work,
although it might be a bit cumbersome. mkvtoolnix will only remux files, not
transcode them, and as such you lose no quality, but cutting is not frame-
accurate (snapped to the nearest video keyframe). FFmpeg can do the same, but
will also let you transcode.
mpv can also transcode and can be used with its own kind of edit decision list
to cut and splice things, but it can't remux.
If you need real video editing capabilities then you can try using VapourSynth
(a scriptable video editing framework similar to AviSynth - warning, steep
learning curve) plus FFmpeg, or Blender's video sequence editor if you want
The latter is actually very good (better than pretty much all other GUI NLEs
on Linux), just a tad bit lacking when it comes to encoder settings.
Note that Blender will have to be built with FFmpeg support for this to work.
For pretty much all video editors to work reliably, you need to get rid of the
MPEG TS container, because nothing is frame-accurate with that (can result in
cuts at the wrong frames and video corruption). To do that, you can try this:
ffmpeg -i input.ts -map 0 -c copy output.mkv
-i input.ts - an input file
-map 0 - tells ffmpeg to map all streams from input file 0 to the output
-c copy - direct stream copy, no transcoding
output.mkv - the output file
Or with mkvtoolnix:
mkvmerge input.ts -o output.mkv
The result should already work perfectly with most software players as well.

See above. I know all this video stuff can be a lot to stomach, and there's an
almost infinite number of things to avoid, so if you need any help or further
advice with this, feel free to email me directly or ask me on IRC
(lachs0r @ freenode).
