Teamblue can be used on them but openvix-atv-pli and a few others toI'm using openvix press blue then select move pip. Then +/- to increase. Does the GigaBlue use its own software?
Interesting to note that it’s only 12 seconds behind the feed.Remember you need access to the satellites you're trying to view. PiP is receiver dependent. Although I'd imagine all the newer ones support this. Mine maxed out around 7/8s of the 4.2.2 feed underneath. The feed was ahead of the live broadcast so I used timeshift on the feed til the live broadcast caught up. It was about 12 seconds behind
