When attempting to view TP 4000/H/29125 DVB_S2 FEC 5/6 on 137W (AMC 7), I get no video, only broken up audio. All channels on the above mentioned TP have the same problem. If I choose a channel on a different TP like 3760/H/25195 DVB-S FEC 3/4, then tune back to TP 4000/H/29125 DVB_S2 FEC 5/6, everything works fine. So, I don't know what is wrong. Has anyone else had this problem? Any comments or suggestions would be appreciated!
