I still use an app called ProjectX. It works very well with my 9200T TS files, so it might be worth a try with the HDR as long as the stream is not HD (DVB-T). It strips all the individual components from the TS stream, and one of those will be an MP2(3) file.
Be warned, however, that it isn’t an intuitive piece of software.
If the Project-x yields you mp2 files these can be edited in mp3directcut (with the addition of mpglib.dll) and then saved as mp3, it’s also good for recording.
