AT&T Videos sudden conversion to RTMPT that can't be downloaded

For almost a year the videos at the URL above were exposed via simple links to the FLV file. Now it appears they've changed over to a RTMPT method. I see an rtmpt URL in the page source for the videos and I've done a core dump of the flash process with the same results. rtmpsrv from git is not able to decode the proper parameters to download these videos. I've also tried many manual options to no avail. Any suggestions? Thanks.
