Hello, all ...

I'm trying to debug a problem where VLC 0.6.0 just goes *poof* after playing a
TS stream (from a server VLC) after 15-20 minutes (it does not always happen,
but I suspect that a somehow 'dirty' TS stream can confuse it).  No core file
is generated, no error messages are output, it just goes away.  I'm attempting
to run VLC under Valgrind to try to isolate what the problem might be, but the
following is output when I try:


[jmzorko at jmzorko2 jmzorko]$ valgrind /usr/local/bin/vlc udp/ts:@239.0.0.20

... any ideas?

Regards,

John
