Sky Latin America is not the answer. They have terrible quality control, lip sync issues, SAP issues, audio level and stereo-mono issues and scheduling issues. The onscreen schedule is wrong half the time and sometimes comes up in French instead of Spanish. You can't see it in English. The English language lineup is bad and the premium channel line ups (HBO, Showtime,etc.) don't match the domestic schedule, i.e. HBO Latin America does not broadcast the linup of HBO E, W or any other, and is a year behind in series content.
As for Dish, I can only answer for my geographic location, which is Cancun. 119 is available most of the day, with some limitations on certain transponders between 3 AM and 8:30 AM. I don't know why that is, but it's a fact. 110 used to be reliable, but lately is becoming increasingly difficult to access no matter which antenna you have. The 6 available transponders go in and out all day long.
