After you press up2. Green button for satellite selection would be great (the TM has a Sat button) and a 1st letter sequence/search is fine if I know which sat I'm on. (Blue button at the moment gives 1. CrossEPG, 2. EPG-Importer, 3. Softcam, 4. ViX Blue Activate PiP)
Ease and time. If it is 1 degree out, adjust yours by the same3. Tuner configuration - is there any advantage to trying to get USALS work, rather than DiSeqc? I only went for the Advanced config because that was where the only mention is USALS was.
