keep us updated, I too am very interested in finding a way to receive mpeg4 hd's while we are camping. I was in the very first wave of directv hd dvr's and thus to run all 7 at our house, we had to have 2 of the huge (to me at least) dishes installed, I understand all kinds of advancements have been made, single line setups, 3 lnb's instead of 5, etc, etc. But I have no idea about how much smaller the mpeg4 hd dishes have gotten, I've always just used a pretty standard tripod (bought it with a dish 500 dual lnb but quickly replaced that dish with a 19" dlnb I had lying around) and just pointed it at single sat and got my tv that way. This year, I believe we are in the same location for 24 days, so the extra effort required to get mpeg4 hd to our trailer seems within reason, please continue to update as I said, I have bookmarked your thread and hope to get some recommendations for what to do.
Thanks in advance.
