GMG are available on west beam but Channels are test cards now. Sometimes they switch to test cards. If you want to get GMG Sport Channels you have to enter audio and video PID values manually.
Yes but only with a High Defination receiver are the GMG channels available (ie for me only on my Spiderbox HD9000 but not for our friend with his Standard Defination echostar receiver) and I did not have to enter any PIDs manually, scaned in automatically fine with no issues whatsoever.......that must be a problem specific to your receiver my friend ETERNAL!!!!
I can't get the East Beam of Turksat myself with my 1.1m Dish and Topfield TF4000PVR, Manhattan DSR 5500 APCI or Spiderbox HD9000.
Does your Echostar have SSSP (RS232) communications connection or a CI Slot or Multicas Card slot? If it does have you tried connecting Fausto Emulator (run from your PC) to your Echostar to solve your SportDigital problem?
