Spectrum just went all encrypted in my area so I have switched to recording off an antenna. I had two 2-tuner HDHomeRuns. One was an original so it is compatible with both antenna and cable. The other I purchased a couple years ago is only cable compatible. 4 tuners had worked for me but with some manipulation to schedules when they had to change channels between consecutive recordings. I noticed the new HDHomeRuns come in 4 or 2 tuner versions. Can EyeTV handle 6 tuners if I got the 4 tuner model? Would I need to start worrying about network or disk speeds? The computer is a mid 2010 MacPro running High Sierra.
