Ok, latest Envivio plug-in for RealOne player will play showcase files from
http://www.psytel-research.co.yu/showcase.htm (http://www.psytel-research.co.yu/showcase.htm)
To test it:
1. download RealOne player (http://www.real.com (http://www.real.com))
2. Uninstall previous envivio plug-in (v1.0)
3. Open the .mp4 file, and Real will automatically download latest Envivio plugin from the Real web site.
I've tested the ShowCase .mp4 files, and they play perfectly. I've also tested our audio+video streams, and they work, too.
