specifically, CBC, ABC, ION muxes, anytime, don't matter. Probably a couple others. Essentially anything that's 720p an S9 will have trouble on almost every f/w except what I'm using now. Same issue with an S10, but a different SW version is required to fix that box.
Another new one just recently dscovered is the new CW mux on Galaxy 17 91W, locks up the box good and tite, unresponsive. No fix for that.
But that mux is all 480i h264, don't think anyone watches that. Deleting that mux was my fix for that issue.
