Tuner A could not be used like I wanted because it could receive APSK transponders, but could not play the APSK channels.
I could never get my SF4008 to recognize the internal hard drive. I tried several.
The LAN or Internet connection quit working or as intermittent. I used a wifi usb device instead.

All these little problems, plus the coding blunders made the SF4008 feel and act like a cheap Chinese box. I am beginning to think it was made in China. Who knows? It has no marks that state the country of manufacture.
