Answer 1

You need to modify your web server configuration such that it serves up the m3u8 file with the correct mime-type. According to this list of playlist formats, an m3u playlist (m3u8 is a UTF-8 variation of m3u) should have one of the following mime types:

Mime type:

audio/mpegurl (recommended)

audio/x-mpegurl

In this technical note Apple say that application/x-mpegurl should be used so I think that's your best bet:

Assuming you're using Apache (quite likely) these instructions should help you configure the server correctly.
