I sometimes use cURL or wget to retrieve HLS playlists and segments and your server is doing something weird. If I try to use wget I get

Retrying.
over and over again until the final 404 when the segment is, I assume, automatically deleted. If I use cURL to retrieve the m3u8 playlist it's fine, but if I use it to retrieve a segment it never completes.
It may be a red herring, but I've never seen anything like that.
More useless information - using some code that uses the old SDK it plays fine on my Roku 3 with firmware v9.2 other than some weird glitching at the start of the stream. Using a different/newer device with newer firmware acts as you've described.
