I found a possible explanation on the dvbviewer forum by Griqa:
" AFAIK the XE stick is not supported by DVBViewer Pro. It requires special means, because it's an USB 1.1 device, that is not able to deliver a whole transponder (like BDA USB 2.0 devices), due to its limited data rate.
That's why the XE has to work with hardware PID filters, which must be set by the application, or with other words, the application must tell the XE which streams of the transponder it wants. Usually BDA devices deliver the whole transponder (so the application gets all streams without requesting them), otherwise they are not really BDA compliant. "
So....
I think I will try to return the stick and get a real usb 2.0 device, or is there another way around this??
Thanks for your attention,
