Description
[23528] increased kDecoderProbeBufferSize from 64K to 1M. For some unknown reason, this is causing the MacOS X client to crash (HDHR, Live TV only):

Sorry to nag, but given that this is a showstopper for LiveTV in 0.23 on OSX, and RC3 is out already, is there a chance that the fix will make it into 0.23 final?
Thanks.

Backported to 0.23-fixes, I can confirm this fixes LiveTV on 10.5/10.6 OS X (Intel).

Believe this should have been closed a bit ago.
Note: See
TracTickets for help on using
tickets.
I can confirm this on OSX 10.6.3 when compiling with osx-packager.pl -m32.
The log can be found on
http://svn.mythtv.org/trac/ticket/8342
but is probably not very helpful.
