Hi,
There is probably a bug in the HbbTV/MHEG 5 plug-in.
I am using Windows 7 64bit and the USB device Aver TV Volar HD Nano. The DVBViewer and HbbTV works fine until the very moment, when I select in the HbbTV application video for streaming (i.e. progressive download). In such a case application shows an error "Exception EAssertionFailed in module VODSource.ax at 0002507F".
I would like to help you to fix the bug, so if I can make logs/traces and provide those to you, please let me know.
Kind Regards,
STeN
