I am still able to capture the stream for this video from AMC with the process I have only ever been able to. Using the HDS Link Detector, firefox add-on works for me. It detects, and captures the entire stream without issue for me. I am not sure what process you had been doing. Please explain if you can. Otherwise, give it a shot. Captures and creates the following code for me, I paste it into Terminal (as I am using a mac) and downloads with KSV's AdobeHDS.php script. Make sure you are up-to-date if this is what you have been doing.
Code:
php AdobeHDS.php --manifest "http://amc350888def-vh.akamaihd.net/z/AMC_Networks_-_AMC/648791619654/240/927/TWD_614_D1_64879264372,5_mp4_video_1280x720_2432000_primary_audio_6,7_mp4_video_1920x1080_8000000_primary_audio_8,6_mp4_video_1920x1080_5000000_primary_audio_7,4_mp4_video_1280x720_1800000_primary_audio_5,3_mp4_video_960x540_1200000_primary_audio_4,2_mp4_video_640x360_568000_primary_audio_3,1_mp4_video_480x270_400000_primary_audio_2,0_mp4_video_416x234_168000_primary_audio_1,.mp4.csmil/manifest.f4m?hdnea=st=1458663073~exp=1458663163~acl=/z/AMC_Networks_-_AMC/648791619654/240/927/TWD_614_D1_64879264372*~hmac=eac064fe2096431eb382686b4817223f9b9124cb00b28cc03266876ed75c7218&g=OYBTKGHFYXKP&hdcore=3.5.0" --delete --auth "hdntl=exp=1458749504~acl=%2fz%2fAMC_Networks_-_AMC%2f648791619654%2f240%2f927%2fTWD_614_D1_64879264372*~data=hdntl~hmac=eaa29d8dd1738a65819f5796eeba16397437a71a8cfd5aa8c7fc10568d37ccf2&als=0,3,NaN,2,0,NaN,0,0,0,103,f,0,2656.39,f,s,OYBTKGHFYXKP,3.5.0,103&hdcore=3.5.0" --useragent "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:45.0) Gecko/20100101 Firefox/45.0"
