Bug Description

I record DVBT2 TV shows as a set of two files, one is the .ts MPEG4 transport stream and the other is .dvr binary file containing EPG program description. On my Ubuntu 14.04.2 LTS desktop those are recognized as follows.

In Nautilus, .ts files are always mapped to text/vnd.trolltech.linguist
file(1) command reports them as either FoxPro FPT or data files

Nevertheless those .ts files are being played correctly when dropped into Totem window.

Program description .dvr files are mapped to video/mpeg in Nautilus, while file(1) command reports them as MPEG sequence, v2, program multiplex. The only exception is info.dvr file not specific to any program and used by the TV set, which is mapped correctly to application/octet-stream in Nautilus and is reported as data by file(1) command.

Attached are the samples of the problematic files recorded by the TV set.
