MY DECA install was done yesterday and it works great. All source-destination combos are smooth and non-jittery and On Demand downloads to both DVRs are good. However I noticed that my install differs quite a bit from what is shown on this group. I'm attaching a jpg for anyone interested and welcome comments from everyone. Again this configuration works great and the Multiswitch, splitter, filter and PI are not overheating so unless I hear that I'm in dire straits I'm gonna leave well enough alone.
