Getting these ABC streams

[guestly]

I'm currently trying to get musical performances from the Jimmy Kimmel Live! ABC website in the highest quality available (720p, 6,000 Kbps) and have had success with Atres Multi-Downloader, however, while selecting any of the M3U8 options (not just m3u8_6902579_1280x720), the TS segments are downloaded and/or merged incompletely compared to the only MP4 version it's able to get (mp4_api1000). I've compared not only length but total number of frames as well between the two resulting files and there's no mistaking there's a difference. I've also tried AVGO Free Video Downloader but it's able to get the 298x168 MP4 and nothing else.

Here's an example of the latest one they have up. I appreciate any help. Thank you.
