Hola!
I'm having some problems with the audio when capturing from SDI or HDSDI 
to my Mac Pro hwen monitoring the capture everything is fine but the 
captured clip has a crackling sound.
I replaced my Decklink extreme 4k with a Decklink extreme 3D and 
everithing is OK.
Anyone having the same problem?
I already reported to BMD and this is the second Decklink Extreme 4k 
board with audio problems.
Thanks

However, that isn't a true test: the exigencies of DMARC are such that (in a nutshell) those subscribers to mailing lists who have accounts at major Email Service Providers like yahoo, aol, et alia (who have implemented stringent DMARC controls), who reply to a message sent via the mailing list to their personal address, and address that reply to the list address (using, for example.    q, Reply-All*) are apt to, based on DMARC's various policy headers, have their reply-post bounce, incrementing the bounce-count at the mailing-list server, which will eventually cause their subscription to be disabled. The intricacies are involved, and are implemented in violation of the Internet Engineering Task Force's standards and precedents, in addition to bypassing the time-proven RFC process.  Because bounce-count and the resulting non-post of the message reply aren't immediately obvious to the replying-poster, the r-p won't know her/his reply isn't going out to the group-at-large for some time (until the bounce threshold is exceeded).

Current policy in the latest Mailman release (2.1.18-1), for the TIG, has the From: header rewritten with "<poster's email> Via Telecine Internet Group" as an experimental workaround. It should be noted, strongly, that this breaks email RFCs and causes unpredictable behavior.

> Other than the various header munging options, which are radical and break the RFCs, nothing else will work for subscribers replying to posts sent to e.g. hotmail, aol, yahoo, and to some extent gmail.  And those munging options are only available in the latest versions of Mailman. If you're using Cpanel/managed hosting you'll either have to wait until they update, or switch to a full self-built host.
