Hello,
We do support this feature.
Please do the following:
1. Make sure that you run the presentation at least for 5-10 minutes to give a chance for the media files to get cached.
Afterwards you can re-start even with no internet connection.
2. RSS does require internet connection, we will add caching system for it in 2-3 weeks.
3. You can email me to mstech [ at ] media ... and I will login to your system and check it out.
But yes, this feature is working and supported.
Regards,
Sean - MediaSignage.com
