Hello Jean-Paul,

I'm affraid this does not fix the problem. I have a TS sample file where 
PCR wraps to 0 and when streaming to RTP [1] (for example) audio is gone 
once the discontinuity occurs.
I can give you this sample, is there a common place to drop it ?

PS : This issue is still in 0.9.x.

[1] : ./vlc -I dummy /tmp/pcr_wrap --sout '#rtp{dst=127.0.0.1}'
