Hi all. I've been setting up a direct publisher channel with Instant TV Channel and S3 over the past week, and it's been going swimmingly, but I'm wanting to switch some of the larger videos to HLS streams to avoid issues on slower connections. I'm hosting the m3u8 playlists on S3/Cloudfront, and they play fine in the browser and VLC, but when I put the link in ITVC, the video loads halfway and then "ends" on the Roku. As far as I know, I'm following all necessary step. Any advice?
