It hadn't occurred to me to try using this with my 'production' el7 box, 
which has ~2500 DVB-T SD recordings that are now mainly in a DVD-style 
mpeg2-ps format.

{{{

   Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, top first), 
704x576 [SAR 16:11 DAR 16:9], 25 fps, 25 tbr, 90k tbn, 50 tbc
     Stream #0:1[0x1c0]: Audio: mp2, 48000 Hz, stereo, s16p, 256 kb/s

}}}

   Selection is fine, but getting to the bottom of the list takes some 
time  :-)  I get no sound, and the video repeatedly plays for a few 
seconds, pauses briefly and moves on.
