You are right. I had not tried viewing on tv1 (assume you meant view on tv1) and recording at the same time but I think what is happening is that we both have our dish boxes so that by default they record on tv2 unless it's already recording something. Then the SA uses tv2 so that you are basically sitting in front of tv2 when viewing the sling adapter.. Then when you watch the same broadcast on tv1 you are simply watching it on both tv's and recording on tv2. If you then try to change the channel on tv2/sling it wants to stop the recording on tv2. You'd probably have to go set the default recording channel to tv1 in the settings in the Record Plus on the dish box...if you want to watch and record and change the channels on the sling. But if you do that you will always have to watch what you are recording on tv1. Does that help?
