First of all I need to tell you that you have an awesome support dep., not to mention the product itself.
Secondly, I'm facing some issues with the SMIL feature: we have a client that wants several streams under the same m3u8 playlist file (probably you know about the Apple's HTTP Streaming requests) and trust me I followed everything related to SMIL in Wowza's Docs and Apple ones and I get an error like unable to download playlist in Media Stream Validator (Apple's Link Validator)
I will attch here some links with the setup - please let me know if I did something stupid.
