2-3 minute delay on streaming to Popcorn Hour NMT

Windows 7 64 bit.

PopCorn Hour A110

There’s a long delay for some reason - not sure why or where to even begin troubleshooting the problem?

Any ideas would be helpful!

I need the user guide of this equipment, plseae can you provide it for me. I need to know one special function, how to get SIS number, where this item is located in menu?
