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
glitch.
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...
