Comment (by Eiffel):

 This bug is very annoying and occurs more often in speech than music. On a
 talkshow, this can be several times per minute.
 I observe it on each DVB-T recording and occasionally in other sources.

 Conversion with ffmpeg shows an "exponent out-of-range" error for each
 However, some errors reported are not audible.

 The same DVB-T sample reads fine for me on two hardware players and with
 MPC-HC v1.3.1249.0 on a very old PC that received tons of codecs and
 upgrades. On the same PC, the glitches occur with VideoLAN player.

 On a new PC, I cannot read this sample with whatever I test. Probably
 because most plyers use ffmpeg...
