So the installer came today and everything went smoothly .. so I thought. Tonight I try to watch TNTHD on 245, but it's unwatchable with artifacting, skipping etc. The other channels look ok. I go to the Satellite Test page on the HR20 and the following info shows on the 1-32 transpoder on the 101 satellite Most everything is 95+ except 4: 42 12:32 20:42 26:0 The HR10-250 shows the same signal numbers as the HR20, but TNT on channel 75 comes in just fine. Can I assume the problem is with the aiming of the dish ? Should I call DTV or is this something I can fix myself? Thanks.
