Dont know what Pinza what talking about with Galaxy 12. Took a look on Lyngsat and that satellite as nothing in it right now. Maybe it was old information and Galaxy 12 changed purpose since.
For jdevlin : if it would of been there, no you cannot pick it up with a bell lnb nor dish. You need a linear lnb and about 30'' dish minimum if the channel is on a KU band transponder. If it's C band, you will the big ol'dish.
Speed was available for a short period of time on 91W, as well as fuel tv and some others. It didnt stay in the clear very long. I dont know if it is available anywhere else or not. If you find it, post it.
if you want F1 racing their use to be a live raw feed back in the day for Speed and TSN and it was on C band but that was like 20 years ago. I am sure F1 is still feed to Speed via a live feed either C band or Ku. I was told once where to find it but forgot, but think the feed was on a Galaxy satellite...
