[QUOTE="Terryl, post: 946480, member: 369937"] I don't think you will find many satellite signal providers broadcasting in 1080i as it takes up a ton of transponder bandwidth, the transponders only have room for about 32 SD channels, and that goes down when they use 720P HD, they have to use some form of compression to get HD channels on the transponders in use today, over here in the US one large satellite provider has changed almost all it's transponders and channels to 8psk modulation and MPEG 4 compression, this may be to get more channels onto a very busy transponder, or in some cases switch to 1080i programming on some. There are a few birds I can pick up that directly broadcast in 1080i and they are the PBS feeds on 125W, but they only have 3 channels on the one transponder. It's all in the allowable bandwidth of the transponder, unless they go to something like 16 or 32 PSK modulation they would not be able to go to 1080i if the transponder is full of channels right now.
