Wow where do I begin? How about as stated in the
rules this site is no hack. So any talk concerning the "cracking" of any encryption is forbidden. Next an FTA receiver receives and decodes DVB MPEG2 clear signals. These are indicated by the F indicator at lyngsat along with DVB. The movie channels you speak of on G10R are big dish stuff. You will never get them on a small dish no matter what receiver you have. Simply not enough gain.
Now we move to the StarChoice dish and lnbf. Could this possibly be a circular lnbf? If so you will not get G10R with that either. So why not start a fresh?
For FTA you will need at least a 31"D. dish (you have) with a linear Ku lnbf and a FTA receiver (that part you do have providing you have not installed any aftermarket software). Take the lnbf mounting arm off the dish and lay it on a flat surface face down. Is it flat on the ground or warped? Warped is junk flat is good. After all you did find it in a dump
Next gather as much info about the lnbf as you can and start doing some homework to determine what it really is. But then again I believe a lnbf can be had for $15.00 so you decide on the amount of homework you wish to invest.
