Hi,
I am trying to stream on demand video using multiple bit rates.
I have a smil file like this (which is called [rm-anatomist-trailer-2.](https://www.wowza.com/community/storage/attachments/504-rm-anatomist-trailer-2.txt)smil on the Wowza server):
rm-anatomist-trailer-2.txt
The HTML page looks like this:
```auto
VideoCentralHD Player (THEOplayer)
THEOplayer test
```
[wpcontent.lgfl.org.uk](http://wpcontent.lgfl.org.uk) has public DNS to the Wowza server and CORS has been defined for the VOD stream.
The player displays correctly but when the play button is pressed the console tab in the browser developer options shows the following error:
theoplayer.js:43 GET [http://wpcontent.lgfl.org.uk:1935/vod/](http://wpcontent.lgfl.org.uk:1935/vod/)_definst_/Anatomist/smil:RM\_anatomist\_trailer\_2.smil/chunklist\_w836646052\_b47100\_sleng.m3u8 404 (Not Found)
This setup works when playing an individual video at a fixed bit rate.
Any assistance will be most appreciated.
Regards
Peter Hall
